Rewriting the nth Term of a Geometric Series with Algebra

Click For Summary
SUMMARY

The discussion focuses on rewriting the nth term of the infinite series represented by the expression (sum from n=0 to infinity) of (π^n)/(3^n+1) into a geometric form. The key transformation identified is (1/3) ∑ (π/3)^n, which simplifies the series into a recognizable geometric series format. This conversion is essential for further analysis and computation of the series. The participants clarify the meaning of "geometric form" and confirm the correct interpretation of the series.

PREREQUISITES
  • Understanding of infinite series and convergence
  • Familiarity with geometric series and their properties

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?

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.
