Step-by-step explanation:

the table below shows the amount of chlorine

f(n), in ounces, that was left in the pool after n weeks:

n    1        2      3     5

f(n)  24     12      6    3

We can see that the value of f(n) is decreasing

f(n) does not have common difference. Lets find common ratio

General rule is f(n) = a1 + (r)^(n-1)

Where a1 represents the first term = 24

r represents the common ratio = 0.5

So the function becomes
