The expression \(\frac{n+1}{n^2}\) converges because, as \(n\) increases, the value of the expression approaches zero.

### Here's a step-by-step explanation:

1. **Break down the expression:**
   \[
   \frac{n+1}{n^2} = \frac{n}{n^2} + \frac{1}{n^2} = \frac{1}{n} + \frac{1}{n^2}
   \]
   This shows that the expression can be split into two simpler terms: \(\frac{1}{n}\) and \(\frac{1}{n^2}\).

2. **Analyze the terms:**
   - The term \(\frac{1}{n}\) decreases as \(n\) increases and approaches 0.
   - The term \(\frac{1}{n^2}\) also decreases as \(n\) increases, but it does so much faster than \(\frac{1}{n}\) and also approaches 0.

3. **Add the terms:**
   - As \(n\) increases, both \(\frac{1}{n}\) and \(\frac{1}{n^2}\) approach 0. Therefore, their sum, \(\frac{1}{n} + \frac{1}{n^2}\), also approaches 0.

4. **Conclusion:**
   Since the entire expression \(\frac{n+1}{n^2}\) tends toward 0 as \(n\) grows larger, we say that the expression converges to 0. The convergence is because both individual components of the expression \(\frac{1}{n}\) and \(\frac{1}{n^2}\) converge to 0 as \(n\) approaches infinity.
