**Ratio Test for Convergence**

To determine the convergence of the series using the Ratio Test:

\[
\sum_{n=1}^{\infty} \frac{n^3}{0.5^n}
\]

The limit of the ratio test simplifies to:

\[
\lim_{n \to \infty} \left| f(n) \right|
\]

where

\[ 
f(n) = \text{(input box)}
\]

The limit is:

\[
\text{(input box)} 
\]

(Enter "oo" for infinity if needed)
