I need help with all three questions please. I am just Stuck.

Step-by-step explanation:

The value of is the first value of the geometric series, that is, .

If the series represents a geometric sequence, then must be constant for every consecutive pair of elements, that is:

Since , .

The geometric sequence can be represented by the following formula:

, for

The 12th element of the geometric sequence is: (, , )

i think the amount would be $140.62

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
