20? Just a guess

The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
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.
