Some geometric mean are inserted between 5 and 80. If second mean is 20, find number of means

 Some geometric means are inserted between 2 and 128. If the third mean is 8, find the number of means.

4 GM  are inserted between 5 and x. If the third mean is 40, find out other means and the value of X.

There are 5 geometric means between a and b. If the second and the last means are 63 and 1701 respectively, find the other means 


Find the number of GMs inserted between 3 and 729, where the ratio of the first mean to last mean is 1:127

Find the number of GMs inserted between 4 and 128 where the ratio of the second mean to last mean is 1:8
