What is the recursive formula for this sequence?

1/8, 1/4, 1/2, 1

5 answers

each term is twice the previous term

An = 2^(n - 4)

Thank you!!!!!!!!!

The recursive formula is
A_1 = 1/8
A_n+1 = A_n * 1/2

from oobleck

The recursive formula is
A_1 = 1/8
A_n+1 = A_n * 2 ... the multiplier is 2 ... not 1/2
