Explanation

To solve the question, "The sum of the successor and the predecessor of 100 is____," we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Predecessor of 100**:
- The predecessor of a number is the number that comes just before it.
- For 100, the predecessor is 100 - 1 = 99.

2. **Identify the Successor of 100**:
- The successor of a number is the number that comes just after it.
- For 100, the successor is 100 + 1 = 101.

3. **Calculate the Sum of the Predecessor and Successor**:
- Now, we will add the predecessor and the successor together:
- Sum = Predecessor + Successor = 99 + 101.

4. **Perform the Addition**:
- 99 + 101 = 200.

5. **Write the Final Answer**:
- Therefore, the sum of the successor and the predecessor of 100 is 200.

### Final Answer:
The sum of the successor and the predecessor of 100 is **200**.
