Explanation

The pattern is: 1 (+4) = 5, 5 (+2) = 7, 7 (*2) = 14, 14 (+4) = 18, 18 (+2) = 20, 20 (*2) = 40, 40 (+4) = 44, 44 (+2) = 46, 46 (*2) = 92.

AI explanation

The series follows a pattern of alternating additions and multiplications. We add 4 to 1 to get 5, add 2 to 5 to get 7, multiply 7 by 2 to get 14, and continue with adding 4, adding 2, and multiplying by 2. Applying the final multiplication step to the preceding term 46, we calculate 46 multiplied by 2 to get 92.
