B Correct answer
Explanation

The series follows an alternating pattern: +6, -4, +6, -4, +6. Following 27, the next step is 27 - 4 = 23.

AI explanation

This alternating series consists of two separate patterns: the first pattern progresses as 17, 19, 21 and the second pattern progresses as 23, 25, 27. The missing term continues the first pattern by adding 2 to the last number in that sequence. Therefore, 21 + 2 equals 23.
