    Start with "1"

    OK, then "1" is one "1" ; that is, "11"

    So then "11" is two ones; that is, "21"

    And "21" is one two, and one one: "1211"

    And that is one one, one two, and two ones: "111221"

    The rest of them follow in the same looney way.

    Examine carefully the following sequences of numbers: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, 31131211131221, 13211311123113112211. Although the sequences appear to behave totally at random, in fact, after the first sequence, each sequence is constructed in a precise and methodical way based on the previous one. What is the next sequence?
