Question
To apply the root test to an infinite series \(\sum a_n\), the value of

\[
\rho = \lim_{n \to \infty} (a_n)^{1/n}
\]

has to be determined. Compute \(\rho\) for the series

\[
\sum_{n=1}^{\infty} \left( \frac{3 \tan^{-1} n}{8} \right)^n
\]

Options for \(\rho\):

1. \(\rho = \frac{4\pi}{3}\)
2. \(\rho = \frac{3\pi}{16}\)
3. \(\rho = \frac{3}{8}\)
4. \(\rho = \frac{3}{16}\)
5. \(\rho = \frac{4}{3}\)
