Question

The first four terms of a sequence are shown below:

7, 4, 1, -2

Which of the following functions best defines this sequence?

f(1) = 7, f(n + 1) = f(n) + 3; for n ≥ 1

f(1) = 7, f(n + 1) = f(n) - 3; for n ≥ 1

f(1) = 7, f(n + 1) = f(n) - 4; for n ≥ 1

f(1) = 7, f(n + 1) = f(n) + 4; for n ≥ 1
