The recursive formula of the geometric sequence is given by option D; an = (1) × (5)^(n - 1) for n ≥ 1
<h3>How to determine recursive formula of a geometric sequence?</h3>
Given: 1, 5, 25, 125, 625, ...
= 5
an = a × r^(n - 1)
= 1 × 5^(n - 1)
an = (1) × (5)^(n - 1) for n ≥ 1

Answer: C
Step-by-step explanation: 5pi converts to 15.70796
0.8=0.8/1=8/10=4/5
not one of them
but,
2/9=0.2222222222
4/9=0.444444444444
7/9=0.7777777777
8/9=0.88888888888
I think you meant 0.8 repeating so
answer is D
Well that symbol is an indention or multiply sign of expression
8,991 which is the product of 999 times 9
