A. write a sequence for the first 3 rebound heights

B. How high is the 6th rebound?

C. Find the sum of all possible rebounds.

I keep getting numbers that are too high. I don't think I have the correct geometric sequence.

2nd 20*(1/4)^2

3rd 20*(1/4)^3

6th 20*(1/4)^6

The sum=20*(1/4+(1/4)^2+(1/4)^3+...)=

20*(1/4)/(1-1/4)=20/3
