Hi, a top secret number sequence is being

typed up line by line. Do you have the code-breaking skills to work out the next line in the sequence?

Good luck! So, there really is very little mathematics

in this sequence. We are simply recording how many of each number appear on each line.

So, in the first line there is just one one, so we write 1, 1. In the second line there

are two ones, so we write 2, 1. In the third line there is one two, and one one. In the

forth line there is one one, one two, and two ones. In the fifth line, there are three

ones, two twos and one one. So, in the final line, there is one three, one one, there are

two twos, and there are two ones. Problem solved!

Before I see the answer I just wanted to type up what I thought it was for most of it. I thought that whatever line u were on then the next line would be that line plus the previous line. example: 1+1 1(2)=3(2 1) 2 1+1 1=5 (1211) 5+3= 8 (111221) but then we get to 10 and the pattern no longer works. Now excuse me as I get back to the video to find out what the heck the solution is

I got my mind think beyooond the solution.. so further to find the pattern

I hate when the solution is easy but you were thinking too much thinking that it is so hard to figure it out
