## badreferences 3 years ago My favorite math pattern:\[1\\11\\21\\1,211\\111,221\\312,211\\13,112,221\\1,113,213,211\]Out of the box thinking! What is the pattern or relationship? If you would please, when you figure out the answer, add the next term in the series, that'd be great. Keep the challenge fresh!

@ParthKohli @KingGeorge @TuringTest

The next element in the series is \(31,131,211,131,221\).

and after that surely is 13211311123113112211

4. shubhamsrg

;)

Haha, you got it. Let's wait for others.

I wonder if it would be possible to define a recurrence relationship for this pattern.

7. shubhamsrg

ahh nice thought,,leme wonder..

Oh, right, @Zarkon YOU GET IN HERE

9. chandhuru

i got it next element will be 31,131,211,131,221.

i like this one

Look and say sequence, knew it in an instant.

14. TuringTest

you are just counting the number of each digit, yes?

15. Libniz

look kinda like pascal triangle

16. TuringTest

1 how many 1s? one 1 (11) how many 1s? two 1s (21) how many of each? one 2 and one 1 (1,211) etc. each entry counts the number of digits... or so it seems to me

17. TuringTest

can somebody please tell me if I am right?

@TuringTest you are 123% right

21. zzr0ck3r

ha thats great

22. TuringTest

hooray! this makes me sleep happy :)
