Question

What is the recursive rule for this geometric sequence?

27, 9, 3, 1, ...

ANSWER: an= 1/3
a1= 27

Answer 1

Answer: a1/3=a((sub)1/3-1)x1/3

Step-by-step explanation: The recursive rule for geometric sequence should be a(sub)n =a(sub)n-1 times the ratio. Given the sequence your ratio should be 1/3.
