Which recursive formula defines this sequence for n > 1?

3, 6, 9, 12, 15, 18, ...

Question 4 options:

an=3an−1

an=an−1+3

an=13an−1

an=an−1−3

(B)

Step-by-step explanation:

Given the sequence: 3, 6, 9, 12, 15, 18, ...

6=3+3

9=6+3

12=9+3

If we continue in like manner, we notice that the nth term () is an addition of 3 to the previous term ().

Therefore (for n>1), the recursive formula which defines the sequence is:

The correct option is B

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.
