In a geometric series, the first term is 108 and the common ratio is \frac{2}{3}. Find the sum of the first 8 terms.

311.36

Step-by-step explanation:

For  a geometric series sum of first n terms is

if r is less than 1.

where a is the first term and r is the common ratio.

____________________________\

given

a = 108

r =

n = 8

thus , sum of n term is

Thus sum of first 8 terms is 311.36
