In #10 I got thought that 3+1=4 ;4×3=12 12+1=13 ;13×3=39 39+1=40 ;40×3=120 120+1=121 ;121×3=363!!!! And Yes This Is My Age!!!! 👇

I think ur mpc Student

[@Seba-ch3yq]

I found the same answer, but differently. I kept moving over to the right, substracting from right to left in pairs of two. 12-3=9 etc. Then, 9 is 3 at the 2nd power, plus the first number in the pair. 120 = 3 at 5th power + 120 = 363

[@aryandas6403]

Bright side also told the same thing.... He just added 3 which ultimately gave rise to 121 120(3)+3=121(3)

[@ethylacetate]

I got mine as 1 saw that the coefficients of 3 are 1, 4, 13, 40 respectively, and are increasing 3, 9, 27... which are powers of 3. 3¹, 3², 3³, then 3⁴ which is 81. 81 + 40 is 121. If 121 is the coefficient of 3, then the next number in the sequence is 3 × 121 = 363

[@buddymack9606]

9:18 6+8+3 does not equal 15; neither will 7+2+4. Swapping 6 and 4 improves the logic only marginally, as not all vertical lines add up to 15. A better approach to this problem is to note that the number in the middle square (5) is equidistant from the numbers on either side of it in any given row; you still get 2 as your answer for the missing entry, but the logic is now made sound.

[@nwdreamer]

Yep. He should have said all the numbers connected by the lines (which all go through the 5).

[@TriNguyen-dl9uu]

Another way to look to look at that riddle is when you add the top and the bottom together, then divide by 2 you will always get 5

[@tonymindsculptor]

Yep, that’s how I solved as well.

[@zanti4132]

He could have created a "magic square" where all rows, columns and diagonals add up to the same number by having 8, 1, 6 on the top row, 3, 5, 7 in the middle, and 4, 9, 2 on the bottom. That is a much better problem esthetically, but he did say he wasn't good as math. :)

[@riya12007]

Buddy Mack only the diagonal ones in that question add up to 15 not the horizontal ones. They made a mistake.

[@DeborahStephenson]

I got them all (a couple took more than 15 seconds, I admit) but the weird thing is that in about half of them, I arrived at the number in a completely different way. For example, on #9, I followed the lines from the outside through 5 in the middle to arrive at a number figured on the right-hand side. The "pattern" went 6-5=1, 8-5=3, 9-5=4 then all that was left that wasn't used by subtracting 5 was 7 (even though the answer would be at the bottom rather than on the right), so 7-5=2. 2 turned out to be the correct answer, but that is NOT how I got it. The others were similar. I guess I just think in a unique way.

[@rvbernier]

Same thing with me!

[@nelsonx5326]

You got them all, dynamite! How old are you? I think the younger minds do better on these kinds of tests. My 67-year-old fossilized brain got 7 right.

@@nelsonx5326 Same age as you, but I took this "test" 4 years ago.

[@Reb0rnLP]

I solved #04 with "3+4=7" and "7-1=6" so the other ones were "5+4=9-1=8" and "2+2=4-1=3". #08 I solved way easier(to me!) than described and still got the same result. 34-4:6=5, so 4+1=5. 53-5=48:8=6, so 5+1=6 again and 47-3=44:11=4, again 3+1=4. Therefore 9*3=27+2=29 (reverse way from what I did before, means 29-2=27:9=3, so 2+1=3). #09 seems to be a only half true assumption. 7+4+2=13 and not 15. This solution of 2 only works if you think about the "1,2,3,4,.." or if you say that only the connected numbers always give 15. Not like what you did with the red circles and saying "each line" in that sense.

[@kvassbo]

Whaaat, on question #09. I thought 2 because the numbers were: 1, ?, 3, 4, 5, 6, 7, 8, 9. It was correct answer but wrong solution!

They weren't connected with a line. Only those that were connected needed to be equal to 15.

[@user-pl9yq3fc8u]

do the fist and last values of each line divided by 2 they must always equal 5 and also im pretty sure he didnt bother to make up his own problems , he clearly just went backwards from the answer to find the solution and also its applicable to the numbers in a line

[@emilyelizabethbuchanan998]

I used different methods but still got the correct answer on #8 and #4. On #8, this is what I saw and used, initially, for the steps: A) Multiply first by whatever the the sum of second+1 is B) Add the original second to the result and you get the third. Went back afterwards and figured that In algebra, with X, Y, and Z to represent the first, second, and third numbers, respectively. So in all three given cases you have: x y z Now, using my method of multiplying x by y+1, then adding y, we get: x(y+1) + y = z This works for all of them, try it. 6(4+1) + 4 = 34 (because 6x5 = 30, then add 4 for 34) 8(5+1) + 5 = 53 (8x6 is 48, add 5 for 53) 11(3+1) + 3 =47 (11x4 is 44, add 3 for 47) 9(2+1) + 2 = 29 (9x3 is 27, 27+2 is 29) I was shocked when their method was different at first, but then I realized, funnily enough, this formula of mine is merely the simplified form of the formula they have given you in the video. They say multiply first and second, then add the sum of the first and the second to the product to get the third. Using X for first, Y for second, and Z for third again, you get: xy + x + y = z For instance, as they said, 6x4 + 6 + 4 = 34. (Since 6x4 is 24, 6+4 is 10, and 24+10 = 34) Of course, xy+x is the same thing as x(y+1). Which is why both formulas work. Furthermore, now that I look at it I realize that you could also solve this problem a third way, by creating the formula y(x+1) + x = z. Since y(x+1) gives you xy+y it's easy to see where this comes from. That would mean you'd multiply the second number by the sum of the first and 1, and then add the first. So to use the example number sequence of 6, 4, and 34, we get: 4(6+1) + 6 = 34 Which holds true since 4x7 is 28, and 28+6 is 34. Pretty cool how that all works out the same! (if you're a math geek like me). Try it with the other two sets yourself if you don't believe me. Now for #4. There are at least five ways to do this, I found. Initially, I actually started with the largest number (the one in the lower right hand corner of the triangle), subtracted the number on the lower left, then added the top number. It worked on all of them too and got me to 10 and 4 for the missing numbers. In Algebra, that would go like this, using x for the number outside the triangle, a for the top number, b for the lower left hand corner, and c for the lower right hand corner. Or: x a b c So: c-b+a=x Remember you have to go left to right with addition and subtraction for this one to work. Again, this formula works for all of them. Try it. 7-4+3 = 6 (7-4 is 3, 3+3 is 6) 9- 4+5 = 10 (9-4 is 5, 5+5 is 10) 4-2+2= 4 (4-2 is 2, 2+2 is 4) Hm. That's not what they said to do to get the answer, though. They said to take the top number (a), add the lower right hand number (c), and subtract the lower left hand number (b), For instance, 3+7-4=6. So their formula would be: a+c-b=x Let's see if you can get this formula from mine. If you take my formula of c-b+a=x and subtract a from both sides, we have c-b=x-a. Now let's simply add a back to both sides and viola! You get their formula. a+c-b=x. Easy peasy. I promised there were three other ways to solve #4. One is very complicated and I doubt if anyone would see it just by looking at the numbers since it involves negative integers. The other two - especially the last - were so easy I was kicking myself for having gone to all this trouble, after finding it. So, first up, the complex solution. If we do another rearranging of the letters we can get them in alphabetical order and have a-b+c=x. This will work for all three groups as well but it involves negatives in the first of the three cases. Again, always go left to right to make it work. Examples: 3-4+7 =6 (3-4 is (-1), 7+(-1) is 7-1, 7-1 is 6) 5-4+9=10 (5-4 is 1, 9+1 is 10) 2-2+4=4 (2-2 is 0, 0+4 is 4) Now wait a minute. Something sneaky is hidden here. Because it's human nature to want to use all three given numbers, we miss two hidden solutions that don't use all the numbers but are much easier than what we've been running around trying to do. And they also can be explained algebraically. Let's take my formula of c-b+a = x again and look hard at the numbers involved in it. 7-4+3 = 6 (7-4 is 3, 3+3 is 6) 9- 4+5 = 10 (9-4 is 5, 5+5 is 10) 4-2+2= 4 (4-2 is 2, 2+2 is 4) Did you catch it? C-b and a are the same number! 7-4 is 3, but a is also 3. 9-4 is 5, but a is also 5. And so on. Therefore: c-b=a So inserting this into our original formula, we can look at this two ways. The first involves getting rid of A altogether and replacing it with the (c-b) it's equal to: (c-b) + (c-b)=x 2(c-b) =x Or, basically, subtract b from c and double the difference. This works in all three cases. 2(7-4) =6 2(9-4) = 10 2 (4-2) = 4 That's a LOT easier, but the fifth method will make you kick yourself, as I did myself, when you realized all of this could have been bypassed by noting on the first triangle that twice 3 is 6. Or, algebraically: 2a=x That's right, you don't have to use b or c at all. You can simply get the correct answers by knowing your 2 times table. 2x3=6 2x5=10 2x2=4 How do you get that from our original formula of c-b+a=x? Easy peasy. Remember I said c-b = a? I just do this: c-b=a, (c-b)+a=x, a+a=x, 2a=x If you read all the way to the end of this you're probably kicking yourself right now, and also you're probably a math geek/pattern lover like me. God Bless! :-)

[@Hi-wn1eb]

For the last riddle you could have done the nth term which would be the difference between 3 and 12 which is 9 and the difference between 12 and 39 which is 27 and the difference between 39 and 130 is 81 and the numbers are 9,27 and 81 and if you, x 9 by 3 it gives 27 and if you x 27 by 3 it gives 81 so you have to do 81 x 3 which gives 243 and you just have to add 243 to 120 and it gives 363

[@marioprawirosudiro7301]

This is how I got to the answer.

[@Deathmark13]

I was very close on the thumbnail question 3 12 39 120 my guess was 390 my logic was that 3 is 1 + 2 so 12 12 is 3 + 9 so 39 although I guess that's where my logic fell apart I was just assuming it would continue to scale like that basically however I was still pretty close because 363 is 3 + 6 + 3 which is 12

I was close to solving no.7 and 8. But yes, these are just awesome. And bro, for the last one there is an alternative correct logic. If you consider that pattern as a series the, you will find that the nth term= 3^1+ 3^2+...+3^n. For example, the first term :- 3^1=3 the second term:- 3^1+3^2=12 the third term:-3^1+3^2+3^3=39 the fourth term:-3^1+3^2+3^3+3^4=39 thus, the fifth term:-3^1+3^2+3^3+3^4+3^5=363

I watched a video from Slavo,he said Bright Side is bad,but he's wrong. It's the BEST!

[@bernard6260]

Lol no

[@lucapelti9766]

Number 10: 39(3rd number)devided by 3(1st number)=13;120:12=10;with this logic the missing number is 39x7(why 7?because 13-10=3 and to keep this difference between the factors we have to do 10-3,that's equal to 7),and 39x7=273. And with this I'm not saying that I think correctly and who made this video does not, I'm just saying that I think you should consider this way to solve it. If you got to this point thank you for your attention and tell me what you think

1st Cool

[@savitajha6375]

9/10 In riddle 6 we can apply another logic.. 2,6,8 36,45,54 18,15,12 So 12 should also be accepted. If it was multiple choice the if option 12 was missing understandable but its not multiple choice so every answer with a reasonable logic should be accepted

[@zlender820]

In #10 I got 3+3squared=12 12+5squared=39 39+9squared=120 120+15squared=345 So the number that gets squared is getting exponentially bigger by 2

[@arshansoleymanianfar854]

Riddle 9: 8 hits 5 and 3 is the out put that can can be seen on the top right (8-5=3), 6-5=1 (the answer cam be seen on the right), 9-5=4 (bottom right), and Finally 7-5=2 (buttom)

For riddle no. 4, other logical answer could be 2 on the vortex of 2nd triangle and 6 on the vortex of 3rd triangle. First multiply the three digits in each triangle and then find their sum. Divide the product with the sum. The result is the number on the vortex of that triangle

[@glennzuniega3838]

#8 (alternative solution) It could also be 6x5 + 4 = 34 8x6 + 5 = 48 11x4 + 3 = 47 9x3 + 2 = 29 For #10 (alternative solution) Simply add 1 then multiply it by 3 (3+1) x 3= 12 (12+1) x 3 = 39 (39+1) x 3 = 120 (120+1) x 3= 363

[@atlanatlanatlan]

I did #09 a different way but I still got it right. Good enough for me.

[@javidhussainzade4481]

On #9 the top row doesn’t add up to 15. The bottom row also doesn’t add up to 15.The left vertical row doesn’t add up to 15. The right vertical row doesn’t add up to 15.

[@Aarreks]

Javido That’s why there is no white line drawn through those rows.

[@javidhussainzade4481]

QQ33 Oops I didn’t realise that.

[@michaelbardov6371]

Another possibility: 1st. triangle: 7-3=4+2=6 2nd. triangle: 4-24-2=2+2=4 3rd triangle: 9-5=4+2=6

[@RiteshKumarMaurya]

In Riddle 9, @ 9:05, First Diagonally, 6 -5 =1, and 5-4 = 1. Again, diagonally, 3+2 = 5, and 5+2 = 7. In middle, 9-4 = 5, 5-4 = 1. This way, 8-5 = 3. So, 5-3 = 2. Thus, 2 should be the answer.

[@krashleywest1]

For No.8 20 is also possible. You start with the biggest number( lets say 34) and subtract the number on the upper right(in this case 4). Then you divide it by the number on the upper left. So 34-4=30 and 30/6=5. All the examples work in this way. So for the final problem, 20-2=18 and 18/9=2 and now we can shake our butts.

[@frankalexander8658]

I got 5 out of 10 correct. Number ten can also be solved by adding 1 to the number being multiplied by 3. 12+1=13×3=39 39+1=40×3=120 120+1=121×3=363

[@andrewrubin4694]

Puzzle 4 can be solved with numerous other answers because there is only one completed series. The question in puzzle 4 does not limit the answer in any way. In puzzle 2, you needn't use the word "rhombus" because the figures are squares. They are set on point, but still are squares.

[@zacharywalchli7427]

#9 u can add opposite sides(line connected) and then divide by 2 to get 5 so the answer would be 2--> (8+2)÷2=5

[@tonygray7171]

No.4. Add the two numbers on the left side of each triangle and the sum is the number on the bottom right in the same triangle then subtract 1 eg.. 3 + 4 = 7 minus 1 = 6 so I get so I get 3 and 8

[@UmerQureshi21]

For riddle #4 I guessed 4 and 10 only because for the first triangle, the number in the top of the triangle was 3 and 3x2=6 So the second tri had 2 in top vertex so I did 2x2=4 Third the top vertex was 5 so 5x2=10

[@DrSlyflyfox]

For #09 I just added the number directly opposite of it across the 5 and divided by 2. Same thing. just different way to get there.6+4-10, 7+3=10, 9+1=10, 8+2=10. All divided by 2 equals 5

[@andyward5214]

This is just for people who want to say they are good at maths through puzzles that are only vaguely related. For you geniuses then, whats n^x^y only one exponent, or ax+by relative to c

[@JSSTyger]

1) 16 2) 2 3) 52 4) 4 and 10 5) 30 6) 11 7) Don't know 8) 11 9) 2 (6-5+4 = 5, 9-5+1 = 5, etc so 8-5+2 = 5) 10) 363 I missed #7 and #8. I'm only 80% genius.

[@existentialchaos8]

In #4, the bottom left number + the top number in the triangles = the bottom right number. In #5, both 20 + 30 and 40 + 10 = the top number, 50.

[@linussakariashansenanderse8528]

I found another solution to #8: you take the bottum and divide it by the top left, and the remaining would be the number on the top right, though this would result in infinitely many answers to the riddle

[@aimlessdisc5993]

I got 9/10 riddles 😂😂

[@ahmedfarooqkhan3797]

I actually got 7/10 correct

[@BazmanTataUniverse]

#9, i’m so lucky, i answer the same number which is 2, simply because the numbers are sequential from 1 to 9, and only number 2 is missing..

[@dankflutertooter4676]

For 8, I multiplied the first number (top left) by the right number (top right) added by 1 then added the right number again to get the solution. So basically L x (R+1) + R, an example is 6 x (4 + 1) + 4 = 34, or 8 x (5 + 1) + 5 = 53.

[@dankflutertooter4676]

Number 9 was pretty easy, you can either look at it and tell 2 is missing, or add the top and bottom numbers, then divided by 2 to get 5. This can be done for the other directions like diagonal or horizontal.

[@arshansoleymanianfar854]

Last one 10:30: 3 times 4*3=12, then 3*13=39,3*40=120, there's a hidden pattern as well all these answers (3,4,39) if you add 1 to all of them gives us the exact multiplying numbers (12+1=13, 39+1=40...) as you can see they all gets added by 1 therefore back to first scenario 3(3+1), 3(12+1)=36, 3(120+1)=363

[@Aricder]

On #9, all the numbers that have a straight line form with each other add up to ten excluding the 5. Ex. 9---5---1, the 9 and 1 adds up to 10. So 8+x=10 and then solve it.

[@bijoylaxmisaha9566]

All right👍👍👍👍

[@krypticzaiden]

For No.10 I went like: 3*3) + 3 = 12 12*3) + 3 = 39 39*3) + 3 = 120 120*3) + 3 = 363

[@girishr4173]

Last one I got it in another logic 3: (3+1)*3=12 12: (12+1)*3=39 39: (39+1)*3=120 120:(120+1)*3=363

[@adunneka8237]

For the fourth question i got my answer through another means: add the numbers at the top of the triangle 3+3=6, 2+2=4, 5+5=10

[@albertoboyoro7136]

riddle #9 another solution Numbers 1-9 ( 2 was missing) or use the line 6-5-4 ( 1 interval) 3-5-7 (2 interval) 8-5- ? (3 interval) so answer is 2 9-5-1 (4 interval)

[@21manishgupta]

Question 8 - I looked at it slightly differently - so I multiplied 6 with the next number in 2nd box 4+1 = 30 and if i subtracted 30 from 34 i got 4. The same is true for all. So 9*3=27-X=2; there X=27+2 = 29

[@JuanLopez-qe1fb]

I think in #10 there’s another answer calculating the differences between numbers: 12-3=9 39-12=27 120-39=81 If you see is the same if you write: 3^2=9 3^3=27 3^4=81 3^5=243 3^6=729 . . . 3^x=to infinite So if we return to the original formula with the differences it’s supposed... 3 , 12 , 39 , 120 , x \/. \/. \/. \/ 9. 27. 81. 243 So, x = 120 + difference = 120 + 243 = 363 And this is another way to solve it

[@荒畑寒村-d3o]

For the last question, I calculated in another way. 3 12 39 120 3 + 1x3 = 12 12 + 1x3 = 39 120 + 1x3 = 363
