    Have you tried reading the digits aloud? :)

    This is a classic riddle - one of my favorites. I won't give away the answer, but here's a hint - try sounding out each sequence in order, like this:

    One
    One one
    Two one
    One two one one

    And another hint -- the next term in the sequence after 111221 starts with 3.

    Good luck!

    Isn't this the one we did on the riddle thread, that I couldn't figure out? And now I've forgotten already. LOL.

    Yes, that's the very one, and I give the same hint every time :p

    I'd say... until the OP posts an answer. This is, nonetheless homework :rolleyes:

    How can this be math homework? There's no mathematical way to figure this out. :confused:

    Well, my first supposition was because it's under the topic homework help... =/

    Oh I agree, I'm just wondering why it's in Math & Science. If it's math, how could you figure it out mathematically? You can't. It's not an equation, the sequence cannot be deciphered using math.

    I'd be more inclined to put it in English homework, but then that would mean the OP has the answer to the question. ;)

    It might just be a math teacher trying to make people think a bit, or even extra credit. I could easily see a teacher doing this, yes. (But I would hope it wouldn't be for normal credit.)
