Question

I need help on an algebra question!

Answer 1

The first four terms of a sequence are shown below:

8, 5, 2, -1

Which of the following functions best defines this sequence?

f(1) = 8, f(n + 1) = f(n) + 3; for n ≥ 1

f(1) = 8, f(n + 1) = f(n) - 5; for n ≥ 1

f(1) = 8, f(n + 1) = f(n) + 5; for n ≥ 1

f(1) = 8, f(n + 1) = f(n) - 3; for n ≥ 1

Answer 2

hmm f(n)-3
