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
Step-by-step explanation:
If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.
Answer:
