Answer:
625
Explanation:
So this says the following:
A term is equal to 5 times the previous term.
We are given the 0th- term is 5.
The first term is 5(5)=25.
The second term would be 5(25)=125.
The third term would be 5(125)=625.
So f(3)=625.
If you didn't like that explanation, you can find f(3), by first finding f(1) then f(2) using the equation given as is without making the interpretation I did above.
