Answer:
The answer is an= 2/3 * 9^n-1
or D
Step-by-step explanation:
The explicit rule is an=a1 * r^n-1
the question tells us that a1 is 2/3, so we plug that into the rule
the question uses the recursive rule ( an=r * an-1) to tell us what r is
r= 9 and a1= 2/3
now lets plug it into our rule
an= 2/3 * 9^n-1
