The sequence appears to be increasing at a variable rate. The pattern seems to be adding 1, then 3, then 5, then 10. Following this pattern, the next number in the sequence would be 20 + 15, which equals 35.

To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96

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.
