What is the formula for 3,12,48,192

3X4^n

Step-by-step explanation:

The sequence is just 3, 3X4, 3X4X4, 3X4X4X4,

so we have 3x4^0, , 3x4^1, 3x4^2, 3x4^3,, 3x4^n

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).
