C Correct answer
Explanation

The differences are: 8-4=4, 16-8=8, 28-16=12, 44-28=16. The differences are multiples of 4. The next difference should be 20. 44 + 20 = 64.

AI explanation

The series follows a pattern based on the differences between the terms, which are 4, 8, 12, and 16. This difference sequence increases by 4 each time, meaning the next difference must be 20. Adding 20 to the last term of 44 gives 64.
