Select ALL the correct answers. Consider the arithmetic sequence below.

Select all functions that define the given sequence.

f(1) = -5, f(n) = - f(n - 1) + 9, for n ≥ 2

f(1) = -5, f(n) = f(n - 1) + 7, for n ≥ 2

f(n) = 9n - 14

f(n) = 9n - 5

f(n) = -5n + 9

f(1) = -5, f(n) = f(n - 1) + 9, for n ≥ 2
