The third term of an arithmetic sequence of positive numbers, in which the difference between the terms is not zero, is the geometric mean of the first and eleventh terms. What is the ratio of the second term to the first term of the sequence?

 

The geometric sequence is basically if you want to find the geo mean of a and b, that's sqrt(ab)

The ratio of the second term to the first term is 8/3.
