Answer

To find the successor of the greatest 5-digit number, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the greatest 5-digit number**:
The greatest 5-digit number is made up of five 9s. Therefore, it is:
\[ 99999 \]

2. **Understand the concept of a successor**:
The successor of a number is the number that comes immediately after it. To find the successor of any number \( x \), we can use the formula:
\[ \text{Successor} = x + 1 \]

3. **Calculate the successor of 99999**:
Now, we apply the formula to find the successor of the greatest 5-digit number:
\[ \text{Successor} = 99999 + 1 \]

4. **Perform the addition**:
Adding 1 to 99999 gives us:
\[ 99999 + 1 = 100000 \]

5. **Conclusion**:
Therefore, the successor of the greatest 5-digit number (99999) is:
\[ 100000 \]

### Final Answer:
The successor of the greatest 5-digit number is **100000**.
