Answer: First three terms are 1/25, 1/5, and 1 in that order.
===========================================================
Explanation:
The fifth term is 25, which makes the fourth term to be 25*(1/5) = 5. We multiply any term by the reciprocal of the common ratio to move back to the previous term.
The third term is 5*(1/5) = 1. The second term is 1*(1/5) = 1/5. The first term is (1/5)*(1/5) = 1/25
Therefore, the first five terms are:
1/25, 1/5, 1, 5, 25
As we move from left to right, we multiply each term by 5. Going in reverse, we multiply by 1/5.
