C Correct answer
Explanation

This sequence has two interleaved patterns: odd positions (2, 4, 6, 8) increase by 2, and even positions (9, 18, 27) are multiples of 9 (9×1, 9×2, 9×3). The next term is the 4th even position: 9×4=36. Options A (10) and B (16) would continue the odd-position pattern instead.

AI explanation

The sequence alternates between two interleaved patterns: the odd-position terms are multiples of 2 (2,4,6,8...) and the even-position terms are multiples of 9 (9,18,27...). Since 8 is the last given odd-position term, the next term continues the multiples-of-9 pattern: 27+9 = 36.
