Explanation
The pattern in the series is a decrease of 4, 8, 4, 2, ... (alternating between subtracting 4 and 8, then decreasing the subtraction by 2 each time).
Therefore, the next number in the series would be:
- 64 - 16 (4 + 8 + 4) = 48
- 48 - 8 (4 + 4) = 40
- 40 - 4 (4) = 36
- 36 - 2 (2) = 34
- 34 - 1 (1) = 33
So, the correct answer is: 33
- 13
- 17
- 19
- None
