Write the successor and predecessor of 999999 and find their difference.

Answer

To solve the problem of finding the successor and predecessor of the number 999999 and then calculating their difference, we can follow these steps:

### Step 1: Identify the Number
The number we are working with is 999999.

### Step 2: Find the Successor
To find the successor of a number, we simply add 1 to it.

\[ \text{Successor} = 999999 + 1 = 1000000 \]

### Step 3: Find the Predecessor
To find the predecessor of a number, we subtract 1 from it.

\[ \text{Predecessor} = 999999 - 1 = 999998 \]

### Step 4: Calculate the Difference
Now we need to find the difference between the successor and the predecessor.

\[ \text{Difference} = \text{Successor} - \text{Predecessor} = 1000000 - 999998 = 2 \]

### Final Answer
- The successor of 999999 is **1000000**.
- The predecessor of 999999 is **999998**.
- The difference between the successor and predecessor is **2**.
