Answer 2

Answer:

15

Step-by-step explanation:

The series is divided into 2 parts.

The first part is 7,8,10,13,17,22. The gap between the numbers is not same. It keeps increasing. The gap between 7 and 8 is 1, the gap between 8 and 10 is 2, the gap between 10 and 13 is 3, the gap between 13 and 17 is 4 and the gap between 17 and 22 is 5.

The part is 3,6,9,12,?. But here, the gap between the numbers is same. The gap between all the numbers is 3. Gap between 3 and 6 is 3, the gap between 6 and 9 is 3, the gap between 9 and 12 is 3. So the next number will be = 12+3= 15.
