    EDIT: someone beat me to it.

    Add the two previous numbers to get the number you want.

    There should be another 1 at the beginning of that sequence.
    No. The sequence is defined such that each term is the sum of the two previous terms. The initial values don't have to be 1, 1 since there is no mentioning of Fibonacci in the question. In fact, the "proper" Fibonacci seq. starts with 0, 1.

    I really don't like questions like this as it suggests there is a single "correct" answer.

    I'm going for 9 and 33 as the missing numbers from u_n = \lfloor 1.552^n \rfloor .
