c

to generate the first four terms, substitute n = 1, 2, 3, 4 into the formula

a_{1} = (3 × 1) + 5 = 3 + 5 = 8

a_{2} = (3 × 2 ) + 5 = 6 + 5 = 11

a_{3} = (3 × 3) + 5 = 9 + 5 = 14

a_{4} = (3 × 4) + 5 = 12 + 5 = 17

the first four terms are 8, 11, 14, 17 → c

The total change in the amount of water in the pool is 288 gallons.

<h3>What is Volume?</h3>

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

Here, Rate of water pumped into her pool = 6 gallons / minute.

          Total Duration = 48 minutes

Total amount of water = Rate X Time
