Find the series...pointers please

[Sriram Krishnan [at] gmx [dot] net]

Given an arbitrary number series, how do I identify the series and find the
Nth number...
for e.g 1,3,5,7 is an AP and the next number will be 9
1,8,27,64 is the series of cubes and the next will be 125
1,1,2,3,5,8 is the Fibonacci series
The thing is I'll be given the series only...I have to identify the series
and find the next number. Pointers on how to do this please ...

Regards,
Sriram
