Answer 20

The first four terms of a sequence are shown below.
8, 5, 2, -1

Which of the following functions best defines this sequence? (4 points)


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 23

You should always ask a new problem in a new post.
Look
8, 5, 2, -1
5=8-3
2=5-3
-1=2-3
What does this tell you?

Answer 24

Each term is equal the term before it -3, starting from the second one.
