Hi,
o) 357 - 486 = -129
f) 4572 + 609 = 5181
b) -12 - 31 = -43
n) - 15 + 8 = -7
Hope this helps.

The given sequence is:
![a(n)= \frac{1}{3} (3)^{n-1}](https://tex.z-dn.net/?f=a%28n%29%3D%20%5Cfrac%7B1%7D%7B3%7D%20%20%283%29%5E%7Bn-1%7D%20)
a(2)=1
a(3)=3
a(4)=9
We are to find the average rate of change between n=3 and n=4 for the given function.
Average rate of change =
![\frac{a(4)-a(3)}{4-3} = \frac{9-3}{1}=6](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%284%29-a%283%29%7D%7B4-3%7D%20%3D%20%5Cfrac%7B9-3%7D%7B1%7D%3D6%20%20)
So the average rate of change for the given function from n = 3 to n = 4 is 6
