The explicit rule for a sequence is given.

an = 2/5(5)^n-1

enter the recursive rule for the geometric sequence.

a1= ; an=

,Recursive formula is :

Step-by-step explanation:

To find a1 we put n=1 in the given Geometric sequence :

Common difference = 2÷ = 5.

r=5.

Recursive formula for a geometric sequence is  

Recursive formula is :

a1=2/5 and an= 5an-1

Just took the test, you're welcome

-2/

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!
