Uhmm... I think I've heard this one before. I don't remember if this is right, but it has something to do with speaking it out loud.

I'm going to guess..

212223?

I agree with Andrea.

The first number in the sequence has one 1. That's 11.

The next has two 1's. That's 21.

Next, we have one 1 and one 2. 1112.

Time time we have three 1's and one 2. 3112.

And so on...

Why did the vector cross the road?

It wanted to be normal.

So the series ends with 21322314? You guys are good! I would have never have seen that relationship. A math problem that does not use math...hmm.

That's what I get. From where ellmp left off, you just need 5 more iterations and then it starts repeating itself.
