Question
Find the interval of convergence of the series.

\[
\sum_{n=1}^{\infty} \frac{(3x)^n}{2^n}
\]

(Use symbolic notation and fractions where needed. Give your answers as intervals in the form \( (\ast, \ast) \). Use the symbol ∞ for infinity, ∪ for combining intervals, and the appropriate type of parenthesis "\( ( \)", "\( ) \)", "\( [ \)" or "\( ] \)" depending on whether the interval is open or closed. Enter DNE if the interval is empty.)

\[ 
x \in \text{[input box]} 
\]
