Question 828345

I'm having trouble solving for a rule for a sequence that goes like this:

{ 9/5, 27/25, 81/125, 243/625....}

I know at least a= something/5^n, but I can't figure out what to do to get the numerator.

Any help please
<pre>
Numerator:    {{{highlight_green(3^(n + 1))}}}
Denominator:  Just as you stated.
You can do the check!!
