Successor

Explanation

### Step-by-Step Solution for Finding the Successor

1. **Understand the Definition of Successor**: The successor of a number is the number that comes immediately after it. In mathematical terms, if \( n \) is any whole number or natural number, then the successor of \( n \) is given by the expression \( n + 1 \).

2. **Identify the Number**: Let's say we want to find the successor of the number \( 4 \). Here, \( n = 4 \).

3. **Apply the Definition**: To find the successor, we will add \( 1 \) to \( n \). So, we calculate:
\[
