A Correct answer
Explanation

There are two series: the first series is 7, 13, 18, 22, 25 and the second series is 8, 5, -1, -10.

The first series is moving on the pattern of +6, +5, +4 and so on, and the second series is moving on the pattern of -3, -6, -9 and so on.

So, the next term is -10 -12 = -22.
