Oh right, sorry about that. As long as we don't spoil the logic though, people can keep trying to figure it out for themselves anyway. :)

This one pops up from time to time in the Brain Teasers forum.
Answer: Not an answer, just how to read the rows.
Except for the first row, each row is a manifest for the row above. That is the first row has one 2 in it. The second row has one 1 and one 2 in it. etc.
