I'm not supposed to have seen this! I am good at these but I can't see it right away, so I'm gonna keep pretending that I didn't see this.

LOL It's a pattern thing! I was trying to do it mathmaticly for 3 days and then thought about dan-e's comment that a calculator or computer wouldn't help. So I started playing with the arrangement of the numbers in patterns. 2 hours later I figured it out.

Whoa! You are a lot more patient than I am! I only tried math, when he told me it wasn't math I decided to wait till he told me the answer.

Simple pattern match& replacement rule :
N - 1N
11 - 21
111 - 31
1111 - 41 etc.
222 - 31
etc.

(longest fit)

Nice !

The sequence is made up by describing the previous line.
ie 1 becomes 11, ie. One number 1
11 becomes 21, ie Two number 1s
etc.
Hope this explains it clearer for you.
