Answers in spoiler tags as usual, please.

I found this puzzle while wandering various puzzle pages, but I can no longer remember which web page was the one where I first found it.

Can you explain? I don't see the reason for this. (I'm hopeless at this "pattern recognition" stuff.)

I'll post the answer with full explanation on Monday or Tuesday. I want anyone interested to be able to have a go without there being an 'official' answer posted.

But here's a clue:
Spoiler:
A similar sequence:

3
13
1113
3113
132113
1113122113
311311222113

I've been looking at this for what seems like ages, and still I got nothing.
I'm sure that if/when I eventually solve it or the solution is revealed there's gonna be a lot of forehead-slapping...

I think Dreams is now feeling justifiably smug.

Keep going - I'm sure with a bit of lateral thought you'll get it.

Clue:
Spoiler:
Try reading the numbers aloud, one digit at a time.

Ok, here's my try:

Spoiler:
Each time we add 10 to each digit. If we get same numbers side by side, we keep only one of them, updating the tens digit to the number of same numbers (I'm not at all happy with how I phrased it, but it works)

So
1
11
11 11 (adding 10 to each digit of the above number. We get 2 11s, so we make them 21)
12 11
11 12 11 11, which again makes 11 12 21
11 11 11 12 12 11, which makes 31 (3 11s) 22 (2 12s) 11
13 11 12 12 11 11, which makes 13 11 22 21
which brings us to the next number, which should be:
11 13 11 11 12 12 12 11, thus 11 13 21 32 11.

You have the right answer. You even have a method that will generate the right answer, and will carry on generating the correct answer for subsequent rows.

But you have indeed expressed the method very clumsily. The way you've written out your answers might help you spot the simple way to describe the method of working out the next line, especially if you try out my clue above.

But quibbles aside — you have the right answer. Congratulations!

Yes, here comes the forehead-slapping!
Why are simple solutions so hard to see?

Smug? Well, maybe not smug, but super pleased that I could finally do a puzzle that made sense to me.

I was beginning to feel like the dumb kid on the block, when all of you could so easily see, figure out, and state the answers so well on the other problems.

I wonder what that says about how I reason or see the world?
