Answer:
Geometric sequence
=54(2/3)^(n-1)
Step-by-step explanation:
Given that a ball is bounced and get up and again hits the ground and bounces up, and so on.
The first height after first hit = 54 inches
Next second peak = 36 inches
III peak = 24 inches
The second peak is 2/3 of first height
and third peak is 2/3 of second height
Thus there is a pattern of geometric sequences such that each peak is 23 of initial peak
IN general nth peak = 54(2/3)^(n-1)

Answer:
28 cubs
Step-by-step explanation:
Since one and a half bear produces one and a half cub, then 6 bears will produce 6 cubs in one and a half days.
We need to find 7 days, though but we have the rate for six bears for 1.5 days which 6 bears one a half day.
What is the rate for a day?
6/1.5 =
6 bears produce 4 cubs a day.
Now just do 4 x 7
4 x 7 = 28
Therefore, 6 bears produce 28 cubs in 7 days.
