2,6,15,31,......
6-2=4=2X2
15-6=9=3X3
31-15=16=4X4
So the next number should be 31+5X5=56
hope this helps :)

Step-by-step explanation:
Given that (x + 8) is a factor of f(x), then x = - 8 is a root and thus
f(- 8) = 0
For clarification, < is less than, > is greater than, and then there is =.
A. So you have to take the percent of each number first.
50% of 20 = 0.5 x 20 = 10
40% of 30 = 0.4 x 30 = 12
Then put in the appropriate sign.
10 < 12
B. 75% of 12 = 0.75 x 12 = 9
30% of 20 = 0.3 x 20 = 6
9 > 6
