Hi! Can somone help me with this question?

 

Evaluate the infinite geometric series:

 

\(\frac{3}{2}-\frac{2}{3}+\frac{8}{27}-\frac{32}{243}+\dots\)

 

Thanks in advance! smiley

The common ration r = -4/9.  The infinite sum is given by a/(1-r), where a is the first term.

 

Can you take it from here?
