Answer:
4782969
Step-by-step explanation:
the equation for finding a term (IN A GEOMETRIC series) is a1(r)^(n-1)
a1=first term
r=ratio
n=the number you want
you can see that the sequence increases by the eponent of 3 increasing y 1 each time. So for the first time 3^0=1,3^1=3, 3^2=9 and so on. So we can determine that the ratio is 3.
so now we can plug all that information into the equation
1(3)^(15-1)=the 15th term
4782969=15th term
Hope that helps :)
