Best ResponseYou've already chosen the best response.0A. f(1)=2 and f(n) = f(n1)+4; n>1 B. f(1) =4 and f(n) = f(n1)+2n; n>1 C. f(1) =2 and f(n) = f(n1) +4n; n>1 D. f(1)=4 and f(n) = f(n1) + 2; n >1 If you could please explain how to get the answer that would be a big help because I have no idea where to even start.

Best ResponseYou've already chosen the best response.0f(1) is the first term, so f(1) = 4. The nth term is f(n), so the previous term would be f(n1). For example, n = 6 for the sixth term, which is f(6). The term before that is the fifth term, f(5), which is the same as f(6  1).

Best ResponseYou've already chosen the best response.0To get each f(n) you need to add 2 to f(n  1), so f(n) = f(n 1) + 2
