The general term of a sequence is given by an = 7+3 (n - 1) for n > 1. Which recursive formula defines this sequence?
A. An = 3an-1; a = 7
O
Ban =
10n-1; a1 = 1
C. An = an-1 + 3; aj = 0
D. An = an-1 + 3; aj = 4
E. Un = an-1 + 3; aj = 7

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
