Question

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

Answer 1

A

Explanation:

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

Here r =
`(a_(2) )/(a_(1) )` =
`(20)/(4)` = 5

Then

f(n) = 5 . f(n - 1) , for n ≥ 2 → A
