**Problem Statement:**

4. Let \( \{ a_n \} = \left\{ \frac{1}{2n^2} \right\} \).

Let \( \varepsilon = 0.001 \).

Find a natural number \( N \) such that \( | a_n - L | < \varepsilon \) when \( n \geq N \).

**Explanation:**

This problem deals with sequences and limits. The sequence is defined as \( \{ a_n \} = \left\{ \frac{1}{2n^2} \right\} \). The task is to find a natural number \( N \) such that for all \( n \) greater than or equal to \( N \), the absolute difference between the sequence term \( a_n \) and the limit \( L \) is less than the small positive number \( \varepsilon = 0.001 \).

The underlying concept is the definition of convergence in sequences, where \( L \) is the limit that the sequence approaches as \( n \) becomes very large. In this case, the limit \( L \) is 0, because as \( n \) approaches infinity, \( \frac{1}{2n^2} \) approaches 0. Therefore, the goal is to identify \( N \) such that for every \( n \geq N \), the inequality \( \left| \frac{1}{2n^2} - 0 \right| < 0.001 \) holds.
