What is the geometric sequence of 1/32, 1/8, 1/2, 2, 8

The formula for the nth term of a sequence with first term a1 and common ratio r is

an=a1 (r) ^ (n-1)

r=a (n+1) / an

to find the common ratio, divide a term by the previous term

8/2=4

2 / (1/2) = 4

(1/2) / (1/8) = 4

(1/8) / (1/32) = 4

common ratio is 4

first erm is 1/32

an = (1/32) (4) ^ (n-1)

The geometric sequence is multiplied by 4
