Question

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 1

The difference is -3.
So \(\normalsize\color{black}{ f_{n+1} }\) = \(\normalsize\color{black}{ f_{n} }\) -3

Answer 2

And `n≥1` in all options.

Answer 3

ok thanks

Answer 4

Anytime :)
