Question

A bouncing ball reaches a height of 27 feet at its first peak, 18 feet at its second peak, and 12 feet at its third peak. Describe how a sequence can be used to determine the height of the ball when it reaches its fourth peak.​

Answer 1

Sample Response:

There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.

Answer 2

Answer: “There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights from a geometric sequence: 27, 18, 12. Two-Thirds of 12 is 8, so on the fourth bounce the ball will reach a height of 8 feet.
