Converting Closed Form to Recursive Formula
$a_1 = 5; a_n = 5*a_{n-1}$

How would i go about converting that to a Recursive Formula?

I just need a jump start on how to find the next term in the sequence, thanks.

hi
well that's already a recursive formula
you can only convert to simple formula i.e.
a_n=5^n

if you need to find the next sequence from the recursive formula
then simply put n=2 and calculate.
