Explanation

The series follows an alternating pattern. The first sequence is 24, 28, 32 (adding 4). The second sequence is 15, ?, 23. Since the gap between 15 and 23 is 8, the missing number is 15 + 4 = 19.

AI explanation

The series alternates between two patterns: the first adds 4 each time (24, 28, 32) and the second adds 4 each time as well (15, ?, 23). To find the missing number in the second sequence, add 4 to 15 to get 19. The result is 19.
