Answer:

D] f(n) = f(n − 1) + (−7)

Step-by-step explanation:

since you already know is an arithmetic series, you have to find the common difference.

87 - 94 = -7

80 - 87 = -7

73 - 80 = -7

the formula for the nth term is f(n) = f(n-1) + d

where f(n-1) is the previous term and d is the common difference, so if youu substitute you get:

f(n) = f(n-1) + d

f(n) = f(n-1) + (-7)

Answer:

A) L = W + 6

B) L * W = 167  OR L = 167 / W

W^2 + 6W -167

Solving by the quadratic formula

Width = 10.266

Length = 16.266
