Write the recursive formula for the geometric sequence a1=-2, a2=8, a3=-32

an+1 = -4an

Step-by-step explanation:

hello :

a2/a1 = a3/a2 = -4 the (common ratio)

the recursive formula for the geometric sequence : an+1 = -4an

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
