Homework Help: The general formula

  1. Jul 20, 2008 #1
    1. The problem statement, all variables and given/known data

    I have to find the general formula of the following series
    m=2, f(m)=1/45
    m=3, f(m)=1/60
    m=4, f(m)=2/175
    m=5, f(m)=1/126

    2. Relevant equations

    3. The attempt at a solution

    I know that there exists some universal fitting models, such as, spline, RBFN and so on. However, the general formula should be monotonic with respect to m and simple in form. Hence, I can not appeal a universal fitting model.
