Finding the formula for a sequence of terms

[@mohamadelharakeh6441]

this will be my last video of this semester . thank you so much for all the work you put in your videos .. you were more helpful than the teacher i paid to be .. again thanks so much for every video you did.

No no no this is very wrong -1(1)*2+(-2)= 0 regardless of these theories it’s an accident because if you only change 1 number or add to one of them it’s NOT going to add up as explained

[@yimengxuezhongwen]

wow the patience you have with those questions I would lose it

[@lolliz100]

That last question that student asked at the end was my concern as well.... Which is: Is there another way of figuring out the Formula other than trying arbitrary methods until it works. Lol. I was hoping that the general format of Arithmetic Progression or Geometric Progression would always easily manifest the formula, but after watching many videos, I've seen that what you all have in common is just trying different operations and mix of operations until it gives rise to the progressing terms. So I guess I can conclude that's the nature and approach of the topic Sequences & Series. But this was nicely reasoned out though, Thankyou.

[@thisrandomdude_]

Woah. Mind blown. This was so interesting to learn! I'm sure it'll come in handy next year, when we deelve deeper into arithmetic series.

[@megsalex4017]

What about this problem... Gregor has decided to create a new sequence that starts with the numbers 4,1,5,6,11,... where each term after the first two terms is found by adding the two previous terms. On the 25th term, his addition was off by . That is, the sum was 1 greater than the correct one. If he made no other mistakes, how far off was the 35th term? Term 1 = 4Term 2 = 1Term 3 = Term 1 + Term 2 = 4 + 1 = 5Term 4 = Term 2 + Term 3 = 1 + 5 = 6Term 5 = Term 3 + Term 4 = 5 + 6 = 11 Thank you so much if u can help I’m just so confused I don’t know at all what to do

Omg thank you

[@alrayhankamal7187]

Can someone tell me the meaning of the (-1)^n? Pls?

[@ksitings763]

So basically if u do -1 to the power of any odd number, u will get -1. If u do it to the power of any even number, u will get 1. (-1)^n is only used for sequences that have both positive and negative numbers

[@rayhanrani3857]

bro this class

[@fufu3768]

Hi, quick question. Where did the "2+1" on the second term went?

[@Dr.PayalHiranwar]

2+1 =3 and (-1) to the power 3 will give "negative 1". Odd powers of (-1) will always give ( -1). And Even powers of (-1) will give value 1

[@konnos06]

Is there another way of representing instead of (-1) to the power of?

[@brianmclogan]

It must me negative for the alternating signes

How can I find the answer to 1, -4, 9, -16, 25? I kinda understand the video but how can i find the explicit formula to the question above?

looks like you are dealing with square numbers n^2 and alternating signs (-10)^n

[@professorthanos1138]

Brian McLogan i have a math homework and the question is find a sub 8 in each of the following sequences and im really confused on how to find the answer

[@brianmclogan]

not sure what sub 8 means

[@remupantoja9302]

maybe plug in 8 to it

[@ashanticarter8537]

How do you do it by finding the 52nd term satrting with 4

[@brianmclogan]

Depends on the type of sequence, here is my playlist for arithmetic and geometric kzbin.info/aero/PL0G-Nd0V5ZMpQxNU0stxlxgHLxYY-Rq1b kzbin.info/aero/PL0G-Nd0V5ZMpZTW9A9qe6JnfyyTwXOaY0

[@justblue9379]

How did u find your n's though?

[@TheQuancy]

Generally we always start with n=1 so, n is usually 1,2,3,4,5,6.... etc n doesnt matter because whatever number u plug in, should result in the same pattern

[@sensui4466]

(n-1) - n(n+1) is another formula for this sequence

[@arulgk9673]

rheaa Yeah that works too

[@barrydavis331]

No, it does not work. Input 1 gets output -2 (wrong) (1-1) -1(1+1) = 0 -1(2) = 0 - 2 = -2 Input 2 gets output -5 Input 3 gets output -10 (wrong)

[@edmariotorio8271]

Its wrong -1square is still -1

[@sparguspargu7014]

Negatives with exponents that are even numbers give you a positive. So -1^2 = 1

[@adrianrainierfabian1852]

-1 x -1 =1

[@simplydannie]

Edmario.. A if you mutliply a negative with another negative, it will be a positive.
