Answer:
2n - 11
Step-by-step explanation:
Note there is a common difference d between consecutive terms of the sequence, that is
d = - 7 - (- 9) = - 5 - (- 7) = - 7 + 9 = - 5 + 7 = 2
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 2, thus
= - 9 + 2(n - 1) = - 9 + 2n - 2 = 2n - 11

So then we do
large-small
V=(1/3)hpir^2
given
small=r=3 and h=5
V=(1/3)5pi3^2
V=5pi3
V=15pi
large, r=5, h=12
V=(1/3)5pi12^2
V=5pi48
V=240pi
large-small=240pi-15pi=225pi in^3
