As it turns out Addison Anderson is actually a cartoon. Who could have seen that coming?

[@Thefitty]

They should narrate a meditation guide ^^

[@011azr]

I agree. However, some people on KZbin don't really like his voice and say that there's something annoying with this kind of voice.

Wow, you mustn't have a life...

[@lucaslayton3974]

Peter Njeim you don't need one when there are ted ed vids.

[@cup_check_official]

Can you find the next number in this sequence? Yes, i can but i am not going to tell you. Do your own homework Ted-Ed

[@superawesomecaptainmcfluff9506]

I know the answer to every mathematical problem that this world has ever seen but I am unable to write them down on this KZbin comment as I have to feed my cat.

Your name doesn't really imply that you know the answer. xD

No that's just the number 42

[@loocie4636]

I like math and school

[@michaelskory7188]

This was really hard, but I eventually figured it out, thank you TedEd for challenging my mind.

[@ideatician4280]

Lol I found my own solution that was possible with the initiating sequence: The rules for my sequence are: 1. Work from last number to the first. 2. If there is a same digit in front of the digit at hand, say ... n n, then replace n n with n+1 n and move to the next digit after this pair. 3. Else put a 1 in front of n and move to the next digit. 1 -> 11 (put 1 in front) 11 -> 21 (n n -> n+1 n) 21 -> 1211 (put 1 in front * 2) 1211 -> 111221 (11 -> 21, put 1 in front * 2) 111221 -> 11213211 (put 1 in front, 22 -> 32, 11 -> 21, put 1 in front) Haha, take that language-based solution!

[@Plonade]

But 111221 makes 312211 though... ¯\_(ツ)_/¯

[@-rc-4873]

Thomas DYOUX lol

[@rolsondimakutosan4643]

You are not that unique.

[@ideatician4280]

Thomas DYOUX Not with my sequence you doofus.

[@ideatician4280]

Rod Delos Santos Did I say something resembling that? Besides, it seems I was the first to discover another solution and publish it in this comment section, so at least I've got that going for me.

[@whatever-sl5zs]

I'll go ahead and say 42, just to be sure

[@LohanRicci]

the answer of everything..

I only knew this because we did work on this very sequence in maths earlier this week

[@omiddorrani9283]

omid dorrani You do know not everybody has the same damn schedule as you

[@snivader]

I also did work on maths sequences earlier this week. Still didn't get it though. I feel like math sequences like this are a whole different genre. That you would look at for like 2 minutes in a class.

[@ReeCocho]

I couldn't help but laugh at the portrait of Conway.

[@daniyalshah1503]

Simple answer: No, I can't.

The fact i got teded riddle right holds so much value in my life. Im so happy

Who tf dislikes Ted Ed videos?

[@sangly3400]

Hiro Kimura the dead brain guy come here and don't understand this vid

[@gmz7283]

bots

[@petros_adamopoulos]

Hiro Kimura i do, because this is actually old. there are older vids about this same thing that explain it much better as well.

[@winstonkzt5411]

Petros, admit it, you are just not smart enough for their videos

[@kittymelon3399]

+Winston Kzt You didn't get the point of that comment....

[@firebrick9045]

I saw that from Bernard Werber's Ants

[@DavidLee-hb8yr]

are you by chance French or Korean? because the book's famous in these two countries

[@imasepan]

정현호 Fun fact: I met Bernard at Kyobomungo last year, pretty cool to see him in person.

[@hammyhamham945]

i love watching ted ed videos but i fall asleep every time, not because it's boring, but because the voice is so soothing. ugh😩 and i have the same problem with michael from vsauce

[@maximusdizon7267]

I saw this in one of the examples of a paul zeitz' book art and craft of problem soling

[@Awesomer929]

One of the few puzzles Ted-Ed has released that I solved within seconds

[@antonspivack3928]

Why isn't this included in the riddles playlist?

[@aliciarouinvy6271]

I haven't watched the video yet but I KNOW the answer is 312211 😝

[@rws531]

Learned this one from RuneScape's hard clues. Dude from Tree Gnome Village gives this riddle.

[@trilloff]

surprised they didn't mention molecule structures as an example. H2O, H2N6, w/e

[@sethgrasse9082]

Lol. I translated it into Base 3 and then looked for a pattern. To much logic, not enough creativity.

[@SamuraiSquash]

I think this is the first TED-Ed puzzle I was able to solve before even clicking on the video

[@willsmith2860]

2:50 that chart of numbers looks like zipf's law to me... It really is everywhere.

[@PartitionZion2]

Nobody: Please Don't Touch Anything: *_how about we take this number sequence_*

[@bradendolezal1634]

Figured out the total from the thumbnail pattern adds the previous one to the in before for the number not sure how it should be displayed though

[@turun_ambartanen]

0:38 it describes the number before it. 1 --> 1 one 1 --> 11 two 1 --> 21 one 2 (and) one 1 --> 1211

[@lovejoymonton369]

without even staring the video, it is 312211

[@lovejoymonton369]

I WAS RIGHT! HAHA

[@akshatsinghai7752]

How did you find this out

[@akshatsinghai7752]

It has no common difference or ratio

[@kyoten4101]

DOPE DOGE it can be pretty obvious, or if you've ever come across it before then it's even easier

[@akshatsinghai7752]

Ani Lu yeah now I get it after watching the whole video

[@excellentdriver]

This is interesting! Another point of view

[@MrCmagik]

Honestly as soon as you see the 3 it's obvious. Before that however, you can actually come up with some mathematical logic (which leads to the wrong answer). So seeing the first answer is kind of required if you want to avoid Lucky answer

[@tty2020]

Saw this question twenty years ago. And figured it out within five minutes.

[@thisismyname8621]

Omg I actually got it. I didn't even read it out loud tho my brain just straight away went to that answer

[@kehindegbadamosi6455]

I figured out a riddle by myself on this channel for the first time :)

[@nicholasemjohnson47]

RIP, John Conway!

[@RowanHumphreys]

I thought a '+' sign was being omitted. 1,1+1,2+1,1+2+1+1,1+1+1+2+2+1...=1,2,3,5,8... (terms found in the fibonacci sequence) and then their was a common ratio of a common ratio between consequtive terms?

[@michaeldedios7866]

I don't know why but I just laughed out loud when I figured it out

[@nori_04]

this is the first time I actually answered one of Ted-Ed's questions. I can die now

[@unknow210]

as always love the puzzle!!

[@jasonprevo2161]

These numbers are in a vr game called, Dont touch anything.. I had no idea what they meant till now.

[@felixlee9645]

More riddles plz.

[@bibekchatterjee8957]

Please complete the pattern 11, 22, -, 77,131

[@dapperfob6194]

I actually found another pattern which works too, Add the 1 and 2's in each number and you get numers as follows : 1 (1) , 2 (1+1) , 3 (2+1) , 5 (1+2+1+1) , 8 (1+1+1+2+2+1) , ... So the next number should be 13 To get 13 just add 2's and 1's in a random sequence : 22222221 (2+2+2+2+2+2+1 = 13) #VapeNation

[@Rippertear]

312211. saw it without even clicking on the video. Now, can you spell icup?

[@maryjane8048]

the only riddle on Ted that I've somehow managed to answer 😂😂

[@gingin4471]

I saw this kind of puzzle at Prof. Layton series once, so I know how to read the sequence 😁

[@lovejoymonton369]

this was once a kind of puzzle in a video game. i think the game was called dont touch anything

[@Zigzag_029]

got it in the three seconds before the answer!!! I confess seeing this pattern before

[@chrysigabriel543]

am i the only one who thought something different than the answer yet it made sence?

[@ylhameresov9492]

I am not a brigt student in class but this seemed to easy to solve.

[@Kaiser_Boog]

The only riddle I was able to solve before I was told

[@hamouz1999]

would like to know how does this apply to other languages

[@massimookissed1023]

I suspect this would have made Lindenmayer happy.

[@fifisteiner2812]

312211. We did this as an exercise when we first studied algorithms for some reason. I wonder what for.

[@vyse3854]

so Catch-22 was derived from that loop?

[@jackspedicy2711]

damn, you got me good, i thinked i had to say one, one, one, two, one. or ignore the , mark... how do you even find these things? my original answer was "a number of 1 is added based on something and then if its 4x1 it turns into 121..."

[@kennymarshall7432]

I figured it out, but only because there's a similar problem is in Knights of the Old Republic.

[@CoronaryTen]

Summation of digits of this sequence follow Fibonacci sequence

[@stefanzylb]

this is like when Peter gives Consuela his number

[@limace]

Yes I can because I read the book "Les Fourmis" from Bernard Werber

[@Skuiggly]

I thought it would be 111122211. There is always a 1 added in the back. For every 2 there is added a 1 in the front.

[@kelvincafirma6898]

When or where will a mirror seption ends

[@kqllr9253]

I actually guessed 3 because it wasnt in it yet and knew it would be a trick question as 1 or 2 would be too obvious

[@abigailvimalasekaran8256]

i figured this out right away with no problem and i don't know this riddle

[@emmalida]

2:13 It's Ziph's Law!

[@jugemujugemugokonosurikire4735]

OH GREAT NOW I SEE IT *AFTER* MY MATHS TEST

[@FluentLee]

This is an answer to a puzzle in runescape lmao

[@RedwoodGeorge]

Wait - RLE isn't used anymore?

[@cubeofcheese5574]

The first 5 numbers added up to Fibonacci numbers so I got stuck thinking it had something to do with that.

[@shubhamsarawagi]

Am I d only person who thought that it was Fibonacci sequence: 1; 1+1=2; 2+1=3; 1+2+1+1=5; 1+1+1+2+2+1=8; I was convinced that my next no. wud total to 13 with 1s and 2s in it. My guess was: 1111221211 Logic was place the earlier no. as it is towards the end and in the later no. push the 2s to the last. Ex:- for 1211 keep 11 and make 21 as 12. Similarly for 111221, keep 21 and make 1211 as 1112.

[@enayetrashid2549]

Mind blowing video that is

[@sixihili1956]

any one has a formula that i can use to generate the next number based on the previous number i know how to find the next number by mind but when the numbers getting bigger it becomes time consuming. so i want a formula or an algorithm that can generate the next sequence

[@jonasrosenkrantz2627]

fibonacci sequence 1,2,3,5,8

[@ALLEZSYS]

Interesting but this rule only applies to the western languages like English. It is not possible or very unusual to make the number countable like two one(s) in Japanese or Chinese that I speak the most along with English. Therefore this is really about the property of English and the concept behind that language system.

[@coldcallerloopy]

3:13 I don't care what anybody says; that's LJN!

[@13PurpleAngels]

Damn I thought it had something to do with the Fibonacci sequence. The digits in the first 5 numbers add up to 1, 2, 3, 5, 8. Thought the next one would add up to 13.

[@Shymuxx]

so easy!

[@hodayapeles9276]

I can't believe that's what I did first thing in the morning.

[@Waltonli1992]

Couldn't it be 11112221? Constantly adding "1" to the 2nd last digit. If it exceed "2", then add a "1" infront and after the 2.

[@seth9326]

Hello Ted-Ed!!!

[@nathanm169]

NintendoGamer 13 hello Nintendo man

[@GraveUypo]

each number is citing quantities of numbers in order on the previous number in the list. that's like the 13th question in a 90 question increasing-difficulty logic test. too easy. i solved right away when i saw the thumbnail. 1 - one 1 11 - 2 ones 1211 - 1 two and 1 one 111221- 1 one, 1 two and 2 ones so the next is 312211 - 3 ones, 2 twos and 1 one [edit] OH COME ON! you gave the damn answer in the video. why did i even bother typing all of this :|

[@mkloven101]

Yes. My maths teacher taught me this back in 9th grade. Next numbers are 312211 i believe.

[@mkloven101]

Idk, it's been a long time so excuse me if i'm wrong lol

[@jollow250]

Yeah no it doesn't always increase that you got wrong for example any number that is greater than 100 and all it's digits are the same will go lower and any number over 9999 that has only a single 1 and the rest 0s will also apply

[@imasepan]

jollow250 yes but if you're following the sequence from 1 or 0, which are meant to be starting points, then that will never happen. But yeah, you are correct.

[@jollow250]

Hurry Calls obviously it doesn't never go up I am saying it doesn't always go up

[@junipiter4689]

Does anyone know what this sequence is called?

[@onthehighlow]

For once I actually solved the puzzle by looking at the thumbnail before watching it to confirm

[@Frantasia]

This is quite hard to solve if it doesn't work in the language you tried to figure it out in.

[@alvarojose3219]

the next number after answer is 13112221 ?

[@shortwhat157]

I guessed it to be triangular momentum , amiright?

[@emilycosgrove1656]

oh I did it in a completely different way that was probably a lot more complicated but it worked

[@SnoopyDoofie]

You didn't figure it out because you saw numbers. An extraterrestrial alien seeing this script wouldn't see numbers but symbols, count the symbols thus automatically derive the next sequence.

[@jejejejrsy9013]

I figured out the pattern when he gave the next number in the sequence (312211)

[@loocie4636]

I FIGURED IT OUT! (Sorta) 🙂

[@geico105]

Why is this video only 17 seconds long?

[@erdvilla]

Consuela would've gotten the answer right away.

[@shakesmctremens178]

Three ones, two twos, and one one.

[@kastandjurdjevic2405]

I actually got it!!!!

[@natep3944]

i legit spent 20 mins on paper trying to do math on this

[@TapadeepChakraborty]

finally I could crack something!

[@MrCotdog]

This is part of a hard clue scroll on Runescape only reason I know it haha

[@trashcentral6778]

Wow I actually knew something for once
