Answer:24
Step-by-step explanation: If the pattern goes 4, 6, 9, then you can see that the distance between the numbers is: 2, 3. Assuming that this is the pattern, the next number would be 4 making it 13, the next number after that would be 5 making it 18, and the next being 6 making it 24.
4, 6, 9, 13, 18, 24
