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
