The next number in the sequence is 27.
The next number in the sequence is 20. This is because the sequence is decreasing by 2, then decreasing by 6, then decreasing by 2, and then decreasing by 6. So, the next step would be to decrease by 2 again, resulting in the number 20.
44 this is based on a sequence of doubling the initial number then adding 2 to that result.
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.
