Question

What is the sum of an infinite geometric series if the first term is 156 and the common ratio is 2⁄3?

Answer 1

Answer:

468

Step-by-step explanation:

If the first term of a geometric series and the common ratio are known, then the sum of the infinite series is

                a

s      = --------------

               1 - r

In this particular case we have:

               156

s      = -------------- = 156/(1/3) = 468

               1 - 2/3
