????????????????????????????????????????

Please put the answer in white, and go as many lines as you can.

Arghh... gets tiring.... I probably made a mistake somewhere in there too... oh well, you get the jist..

It's not really hard, but what are all the extra 1's for in your first answer?

 Kinda fun, that one is. I had one of my friends on that for about a week one time, trying to solve it mathematically. Paden Roder

 Quote by mabs239 Its a really good brain teser. But is there anything special about the series other than that?
Not really. Let's see...

There's only 1 number that starts off with a 2-- all the rest start with 1 or 3. All of them end in a 1.

Each digit in the series (left-aligning them) results in a 3-or-less length repeating sequence. So the 3rd digit (say) gets stuck in a loop starting at the 8th number in the series, repeating "1", "1", "2", such that the Nth number in the sequence's 3rd digit is predictable for N>=8. Each place follows a similar pattern with a loop length of 3 or 1. The 5th digit (for example) is always 1 starting at the 9th number in the sequence. And right-aligning the numbers results in 4-or-less length repeating sequences.

For each number in the sequence, if there are A 1's, B 2's and C 3's, then A >= B >= C. The percentage occurrences of 1's, 2's, and 3's seem to be convergent to roughly 49.5%, 32%, and 18.5% respectively (looking down to about the 50th number in the sequence).

There are probably some more things on that level of interesting, but nothing unexpected.
