Answer:
Explicit formula is
.
Recursive formula is 
Step-by-step explanation:
Step 1
In this step we first find the explicit formula for the height of the ball.To find the explicit formula we use the fact that the bounces form a geometric sequence. A geometric sequence has the general formula ,
In this case the first term
, the common ratio
since the ball bounces back to 0.85 of it's previous height.
We can write the explicit formula as,

Step 2
In this step we find the recursive formula for the height of the ball after each bounce. Since the ball bounces to 0.85 percent of it's previous height, we know that to get the next term in the sequence, we have to multiply the previous term by the common ratio. The general fomula for a geometric sequene is 
With the parameters given in this problem, we write the general term of the sequence as ,

-9,-3,3,9,-9,-3,3,9 so forth until -3
The word "difference" means "subtract" so B. Wouldn't be B. Because it's adding. This leaves us with A,C, and D
For A. It's a positive one (so this can't be your answer)
For D the negative one is in the front
The question isn't asking the different -1 and -12
So, this leaves us with option C as your answer
Good luck on your assignment and enjoy your day!
