    What is the algebra required to rewrite the nth term of: (sum from n=0 to infinity) of (pi^n)/(3^n+1) in geometric form?

    Welcome to PF!

    Hi ollybabar! Welcome to PF! :smile:

    (have a pi: π and an infinity: ∞ and try using the X2 tag just above the Reply box :wink:)
    I don't understand your question …

    what do you mean by "geometric form"? and so you mean the sum of the first n terms? :confused:

    Anyway, it'll help if you rewrite it: (1/3) ∑ (π/3)n :wink:

    I've figured it out; thanks for the reply though.
