The answer is 24. To get from one term to the next, you have to find the difference. To get from 52 to 45, you minus 7. It is the same with the other terms. So 31 - 7 = 24
The -9 stays the same the whole time but the other number being multiplied decreases by one each layer, so the next three would be:
-9 x -1 = 9
^^^ -1 is in the second multiplication slot bc 0 - 1 = -1
-9 x -2 = 18
^^^ -2 is in the second multiplication slot bc 0 - 2= -2
-9 x -3 = 27
^^^ -3 is in the second multiplication slot bc 0 - 3 = -3
***Remember that when you are multiplying two negative numbers the solution will be positive

Answer:
125.660 cm^2
Step-by-step explanation:
Surface area of a right cylinder is A=2πrh+2πr^2
π= 3.14
h= 8 cm
r= 2 cm
A=(2)(3.14)(2)(8) + (2)(3.14)(2)^2
