Question
𝑎, 𝑎𝑅, 𝑎𝑅2, … , 𝑎𝑅𝑛−1 (2)
Find the sum of the geometric sequence in (2), denoted by
𝑆𝑛.
In finance problems, the number n may be the number of months or years. The number R is the compounding factor given by (1+r), related to the rate of interest, r. Each finance problem is unique and applying the geometric series formula upfront may lead to wrong answers.

i'm confuse with this question..can somebody help me?
oobleck
Sn = a(1+R+R^2+...+R^(n -1)) a(R^n - 1)/(R-1) = a/r (R^n - 1)
