- Let's analyze the sequence: 11, 12, 13, 13, 17, 16, 23, ?, ?

- The sequence alternates between two different sequences:

- First sequence: 11, 13, 17, 23 (increases by increasing odd numbers: 2, 4, 6)

- Second sequence: 12, 13, 16 (increases by 1, then 3)

- Continuing these patterns:

- First sequence: After 23, add 8 ? 31.

- Second sequence: After 16, add 5 ? 21.

- Evaluation of options:

- Option 1: 21, 31 - Matches the pattern.

- Option 2: 25, 33 - Does not match.

- Option 3: 23, 27 - Does not match.

- Option 4: 23, 29 - Does not match.
