\[a_{n}=a{1}r^{n-1}\]
r=16/8=2
a_{12}=8(2)^{12-1}
The answer is c. You do:
8•7•6•5
There are 8 fruits that you can choose from and every one of them can go with 7 different fruits which can go with 6 different fruits which can go with 5 different fruits.
You do that thing four times because you said that he can choose 4 fruits.
The answer to the first part of your question is 9
as for the second part 36/4 (which is 9 btw) then subtract 2 I answered this one the best I could (let me know if I'm wrong)
(i just don't have to much time on my hands because I have homework myself)
