Best ResponseYou've already chosen the best response.1Right, \(S_{10}\) means the sum of first \(10\) terms : \[S_{10} = 1 + 4 + 4^2 + 4^3+\cdots + 4^8 + 4^9\] just check if we have exactly \(10\) terms in above sum

Best ResponseYou've already chosen the best response.2note: This is a geometric progression :) So, if you want to find the sum of the first 10 terms, you would use this formula: \[S_n = \frac{ a(1r)^n }{ 1r }\] n = nth term, r = common ratio, a = first term
