- 4. Multiple ChoiceWrite the explicit rule for this situation.f(n) = 35 + 3(n − 1)f(n) = 35 −3(n − 1)f(n) = 3 + 35(n − 1)f(n) = −3 + 35(n − 1)
- 5. Multiple ChoiceWrite the recursive rule for this situation.f(n) = f(n − 1) + 58, n ≥ 2f(n) = 58 + 7(n − 1)f(n) = 58 − 7(n − 1)f(n) = f(n − 1) + 7, n ≥ 2
