Find the common ratio of the geometric sequence.
100, 50, 25, 25/2, ...

Step-by-step explanation:

simply divide second term by first term and then third term by second term... if the ratios are equal, they are geometric series and that's their common ratio.

the answer is 0.3175 hope that you ^w^
