One and three.
It is 20, the number in the middle when they are arranged in order.
The sequence of differences between consecutive numbers is 9, 1, -20, 9, 1. If this continues then the next difference is -20 and therefore the seventh number is -5. (15 - 20).
No
24 * .15 = 2.4 + 1.2 = 3.6
One and three.
1 and 3 will go into both numbers evenly

15, 15, 20, 24, 25, 25, 30 Mode: 22 Median: 24

No
10/12 15/18 20/24 ect...10/12, 15/18, 20/24
24 * .15 = 2.4 + 1.2 = 3.6
No. The pattern is: +9, +1, -20, +9, +1, -20... So the next five numbers are: -5, 4, 5, -15, -6.
I believe it is 120, because 8 will go into 120 15 times, 6 goes into it 20 times, and 5 goes into it 24 times. This is the lowest posible multiple
