    Post Sequence Problem

    Hi, All,

    Recently, I got a sequence problem which is:

    a_{n} = a_{n-1} - \frac{a_{n-1}^2}{m-S_{n-2}}
    where S_n is sum of a_i, i = 1,2,...,n, m is an integer.

    Does anyone have some idea on a_n or S_n about their analytic expressions, not recursive expressions?

    Thanks,
