    Yup! Would be appreciated if you used [ color = ededed] and [/color] so that others can figure it out without seeing the answer as well. :) Its ok though :-p

    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. :)

    If you don't mind me asking, how did you do it?

    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.
