    The next rows are:

    13211311123113112211
    and then
    11131221133112132113212221
    (each line tells you what was in the previous line)
    but this is not number theory; it should be in the brain teaser section.

    Also, it's been done already in the Brain Teaser subforum...but is an fun puzzle, nevertheless - requires some out-of-the-box thinking.
