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.
