In this item, we assume that f(6) is the f(n + 1). Thus, n + 1 = 6. If we solve for the succeeding terms for this series given the first term which is 100, we get,
f(2) = 100 – 8 = 92
f(3) = 92 – 8 = 84
f(4) = 84 – 8 = 76
f(4) = 76 – 8 = 68
f(5) = 68 – 8 = 60
f(6) = 60 -8 = 52
Thus, the answer is 52.
