### Power Series Representation and Radius of Convergence

**Problem Statement:**
Find a power series representation for the function.

\[ f(x) = \frac{x}{(1 + 4x)^2} \]

The function \( f(x) \) is given as:

\[ f(x) = \sum_{n=0}^{\infty} \left( (-1)^n \right) \times \]

**Determine the radius of convergence, \( R \).**

\[ R = \underline{\makebox[1in]{}} \]

This problem involves representing the function \( f(x) = \frac{x}{(1+4x)^2} \) as a power series and determining its radius of convergence \( R \).
