The _______ of a given whole number is 1 more than the given number.

Options

A. Predecessor
B. Successor
C. Inverse
D. Identity

Answer

To solve the question, we need to fill in the blank with the correct term that describes a number that is 1 more than a given whole number.

### Step-by-Step Solution:

1. **Understanding the Problem**:
- We need to find a term that represents a number which is 1 more than a given whole number.

2. **Defining the Whole Number**:
- Let’s denote the given whole number as \( n \). Whole numbers are non-negative integers starting from 0 (i.e., 0, 1, 2, 3, ...).

3. **Finding the Number that is 1 More**:
- To find a number that is 1 more than \( n \), we can express it mathematically as \( n + 1 \).

4. **Identifying the Term**:
- The term that describes \( n + 1 \) is known as the "successor" of \( n \). The successor is defined as the next whole number in the sequence.

5. **Final Answer**:
- Therefore, the blank can be filled with the word "successor".

So, the complete sentence is: "The **successor** of a given whole number is 1 more than the given number."
