Question

Complete the recursive formula of the geometric sequence 500, 200, 80, 32, ....

Answer 1

Answer:

times 0.4

Step-by-step explanation:

The recursive formula allows a term in the sequence by multiplying the previous term by the common ratio r

Here

r = $\frac{200}{500}$ = $\frac{2}{5}$ = 0.4

Thus the recursive formula is

c(n) = c(n - 1) × 0.4 → with c(1) = 500 ← the first term in the sequence
