Determining a formula for a (sub)sequence

  1. Feb 21, 2014 #1
    I currently have the first 125,256 terms of a sequence of natural numbers. I need to find a formula for any non-finite sub-sequence.

    Are there any good methods for obtaining such a formula? I can already say that it isn't a linear distribution, and I highly doubt it being polynomial (although it could involve a root function).

    Any help would be appreciated.

    Thanks.

    How did you get the sequence?

    The sequence is the set of n's where | ∑[itex]_{k=0}^{n}[/itex] a[itex]_{k}[/itex]z[itex]^{k}[/itex] | is a local maximum in the sequence of the magnitudes of partial sums (the partial sums are complex valued).
