Question

Explicit equation for the sequence

Answer 1

Step-by-step explanation:

when we get the common ratio that  must be equal

r=6/2=18/6=54/18=3    equal

So it is geometric

By using this equation:

a(n)=a(1)*r^(n-1)

and we have a(1)=2 , r=3    

Explicit rule: a(n)=2*(3)^(n-1)

hope this helps
