Question

Plzzz Help! Determine the recursive function that defines the sequence.

Answer 1

Answer:

A

Step-by-step explanation:

The recursive rule allows any term to be found by multiplying the previous term by the common ratio r

Here r = $\frac{a_{2} }{a_{1} }$ = $\frac{20}{4}$ = 5

Then

f(n) = 5 . f(n - 1) , for n ≥ 2 → A
