A1 = first term = 8

Plug in a1 = 8:
an = 8 + (n - 1)d

FInd d:
Given that a2 = 5
5 = 8 + (2-1)d
5 = 8 + d
d = -3

Plug in d = -3:
an = 8 -3(n - 1)

Answer: an = 8 -3(n - 1) ; n ≥ 1

The average price (in dollars) to rent a studio in a certain city can be approximated by the equation p=28.2t+644 where t is the

egoroff_w [7]

$p = 28.2t + 644\\\\p-644 = 28.2t\\\\\frac{p-644}{28.2} = \frac{28.2t}{28.2}\\ \\t = \frac{p-644}{28.2}$

$t = \frac{1320.80-644}{28.2} \\\\t = 24$

It will take 24 years.
