I've tried to get the answer for this 13 times now (not joking), plzzz help: write a formula that represents the number of peopl

Answer:

2820 seats
aₙ = 3n + 9

Step-by-step explanation:

This is an AP with:

The first term a₁ = 12
Common difference d = 3
Number of terms n = 40

Number of the seats:

Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats

Formula of nth term:

aₙ = a₁ + (n - 1)d
aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
aₙ = 3n + 9
