Question

Help!! The first four terms of a sequence are shown below.

6, 2, -2, -6

Which of the following functions best defines this sequence?
f(1) = 6, f(n + 1) = f(n) + 4; for n ≥ 1
f(1) = 6, f(n + 1) = f(n) - 2; for n ≥ 1
f(1) = 6, f(n + 1) = f(n) - 4; for n ≥ 1
f(1) = 6, f(n + 1) = f(n) + 2; for n ≥ 1
