57 chairs because you are given the needed information to solve the answer. There will be 456 people attending so you need to divide that by 8 to get your answer.
A1 = first term = 8
<u>Plug in a1 = 8:</u>
an = 8 + (n - 1)d
<u>FInd d:</u>
Given that a2 = 5
5 = 8 + (2-1)d
5 = 8 + d
d = -3
<u>Plug in d = -3:</u>
an = 8 -3(n - 1)
Answer: an = 8 -3(n - 1) ; <span>n ≥ 1</span>
