## Homework Statement

Determine whether the series is convergent or divergent. Find the sum if possible

Ʃ 1+2^n / 3^n n=1 -> infinity

## Homework Equations

a/1-r

## The Attempt at a Solution

I split it up so that the equation is now:

Ʃ (1/3^n) + (2/3)^n n=1 -> infinity

Ʃ (1/3^n) + Ʃ (2/3)^n n=1 -> infinity

I know that it is convergent in the second term because 2/3 < 1, how do I setup a/1-r for term 1? :S

a1=1/3 a1 = 2/3

(1/3)/(1-(1/3)) + (2/3)/(1-(2/3))

=5/2

The answer should be 3/2 on the answer sheet it says ?
