Find Numbers Before and After 9099: Complete the Sequence

To solve this problem, we'll follow these steps:

• Identify the given number, which is 9099.
• Step 1: Compute the predecessor by subtracting 1 from 9099.
  The predecessor is $9099 - 1 = 9098$.
• Step 2: Compute the successor by adding 1 to 9099.
  The successor is $9099 + 1 = 9100$.

Now, let's confirm with the available choices:

We calculated the predecessor as $9098$ and the successor as $9100$.

Therefore, the correct sequence filling the blanks is:

$9098, 9099, 9100$

Hence, the correct answer from the given choices is:

Choice 2: $9098, 9100$
