Answer:
-40
Step-by-step explanation:
-4 * 2 = -8
-8*-1= 8
12+8 = 20
20*(-2) =-40
The solution to the problem is as follows:
Just plug in the numbers and follow the pattern.
a0 = 1
a1 = 2*1 + 2 = 4
a2 = 2*4 +2 = 10
<span>a3 = 2*10 +2 = 22

I hope my answer has come to your help. God bless and have a nice day ahead!
The volume of the water storage tank is the amount of space in it
The volume of the water storage tank is 6468 cubic feet
<h3>How to determine the volume?</h3>
The given parameters are:
Radius (r) = 21 feet
Height (h) = 14 feet
The shape of the water storage tank is a cone.
And the volume of a cone is:
V = 1/3πr^2h
So, we have:
V = 1/3 * 22/7 * 21^2 * 14
This gives
V = 6468
Hence, the volume of the water storage tank is 6468 cubic feet
