PEG - Here is 'A good mind teaser'

The following are the first few terms in a sequence of numbers. Can you figure out the next few terms and describe how to find all the terms in the sequence ???
Hints: This could be called the “Say The Sequence” problem.
1
11
21
1211
111221
312211
My Daughter brought this home from school and I had it figured out in less than 2 min. Even her math teacher didn't know the answer. ME THINKS I GOT LUCKY - But my daughter was very proud of her Pop!
LOL not me!

The sequence is formed by reading the previous term: for example, the term after 111221 is 3 'one's, 2 'two's, 1 'one' (or 312211).
Then we read it: 1 three, 1 one, 2 two's, 2 one's, or 13112221 and then this reads...1 one, 1 three, 2 one's, 3 two's and 1 one or 1113213211 and so on.
DOSMAN IS 100% CORRECT

I am posting this reply for BetiCan as he has just passed away today @ 11:35 am (cst). We were very close as you can imagine and I know all too well how his twisted, demented mind worked. I want to thank Dosman for not divulging how it was figured as it can still be a challenge for someone else. I am sure that if this gets soooooo frustrating for someone that they can't sleep & or function that BetiCan (now me, as his legal heir) or Dosman will be glad to forward the solution for a nominal fee of say $100.

So not as fast as Betican. I had scrolled down and caught a glimpse of DOSMAN's answer, but didn't write it down or study it, and scrolled back up quickly so I didn't to see the explanation.
I'm going to spring this one on my brother tomorrow. He thinks he's so smart!

At GameColony.com you can play games of skill only -- play for free or play for $prizes!.
According to the statutes of most states in the United States, gambling is defined as: "risking something of value upon the outcome of a contest of chance". (Also see No Gambling!). The skill (as opposed to chance) is predominant in games of skill. Playing games of skill for $prizes, therefore, has nothing to do with gambling as it is not a contest of chance -- the more skillful player will win far more often. The chance element of a 'gamble' is either insignificant or missing. When players compete in tournaments or games of skill for $prizes -- it is "competitive entertainment" rather then "gambling". The more skilled winner will always win more matches, tournaments and $prizes.
