A Correct answer
Explanation

The series consists of two alternating sequences: 2, 10, 18, 26 (increasing by 8) and 7, 22, 37, ? (increasing by 15). The next term is 37 + 15 = 52.

AI explanation

The series alternates between two separate patterns. The first pattern increases by 5, then 8, then 8: 2 + 5 = 7, 10 + 8 = 18, and 18 + 8 = 26. The second pattern is 7 + 15 = 22 and 22 + 15 = 37. The missing number continues the second pattern by adding 15 to 37, yielding 52.
