A simple number sequence I made

Postby rileyrulesu » Thu Jan 21, 2010 11:18 pm UTC

I made this when i was about four years old, have fun trying to solve it!

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


so, what comes next, and how do you know?

p.s. its kind of simple, this was before i knew there was harder math than division

It's a fairly well-known sequence with some interesting properties: http://en.wikipedia.org/wiki/Look-and-say_sequence
