\[
\begin{aligned}
&\text{If the coefficients of } x^7 \text{ and } x^8 \text{ in the expansion of } \left( 2 + \frac{x}{3} \right)^n \text{ are equal, then the value of } n \text{ is:}\\

\[
\begin{aligned}
&\text{If the constant term of the binomial expansion of } \left( 2x - \frac{1}{x} \right)^n \text{ is } -160,\text{ then } n \text{ is equal to:}\\
