Arithmetic and Geometric Sequences (Context).A bouncy ball is dropped such that the height of its first bounce is 6.75 feet and each successive bounce is 68% of the previous bounce's height. What would be the height of the 6th bounce of the ball?

We have:

Let b = bounce height = 6.75 feet

p = percent of bounce height = 68%

And the formula of the height of nth bounce is:


h=b\cdot p^(n-1)

Then for the 6th bounce:


h=6.75*0.68^(6-1)=6.75*0.68^5=0.981

Round to nearest tenth = 1.0

Answer: 1.0 feet
