Show answer & explanation
Correct answer: A
Answer: 19 33
Explanation:
The sequence is made by interleaving two patterns:
An arithmetic sequence of odd numbers starting at 9 and increasing by 2: 9, 11, 13, 15, 17, 19, ...
The constant number 33 inserted at every third position.
Map the given terms to positions to see the pattern:
Positions 1–7: 9 (1), 11 (2), 33 (3), 13 (4), 15 (5), 33 (6), 17 (7).
Therefore positions 8 and 9 are the next arithmetic term 19 and then 33.
