oh what the hell...everybody else is posting challenges..

[8*B@LL]

tho i dont think this is really crypto. anyway, whats the next number in the sequence:
1, 11, 21, 1211, 111221

[fiend]

My head hurts.

[ThePreacher]

1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211

Do I get a prize?

[ThePreacher]

i can take it further too

31131211121221, 13211311123112112211, 11131221123112132112212221

i can do this forever.....lol

[redsca]

Will somebody please explain it.

I'm going MAD !!!.

[morfius]

My head hurts.
:(

Guys, do a search and you'll find the answer if you don't already know it like The Preacher does.

It's just a numbers sequencing problem. Think logically and you'll see.


I'll give you a hint, it's known as Conway Sequence.

[blow]

The integer sequence beginning with a single digit in which the next term is obtained by describing the previous term. Starting with 1, the sequence would be defined by "1, one 1, two 1s, one 2 one 1," etc., and the result is 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211

Thats the explanation, i think.

[blow]

thx for the hint texie chick

[8*B@LL]

awwww...well that didnt take long :-(

[ZeroOne]

I still didn't get it even after blow's message (which by the way was a direct quote from http://mathworld.wolfram.com/LookandSaySequence.html ....). I had to click there a link that directed me to http://www.research.att.com/cgi-bin/access.cgi/as/njas/sequences/eisA.cgi?Anum=005150 which gave an example I finally also understood :):
Example: E.g. the term after 1211 is obtained by saying "one 1, one 2, two 1's", which gives 111221.
Hope this helps someone else too who doesn't dare to ask....

[fr0z3n]

lol poor 8*b@ll its okay.. you can do a better challenge =)

[8*B@LL]

hehe, fr0z3n, i did. check out my other challenge thread (entitled "this one's a toughy(or atleast i think so)" ).

so far i have everybody completely stumped, though it doesnt seem many people are attempting it.
