    Sequence Puzzle

    11
    21
    1211
    111221
    ??????
    ????????


    The sequence above is a number puzzle. It should be read left to right, top to bottom.

    Complete the last two rows of numbers? Explain how you got them.

    Hint: This puzzle could've been placed in the non-mathematical sub-forum as well.

    The solution is to read the digits in the number... for example 1211 is made by 1 one,1 one and then 2 ones
