Question 1003398: Find the sum of the four geometric means between 160 and 5.

Since there are four means, there are five multiplicative steps going from 160 to 5...another way of showing that is...
160r^5 = 5
r^5 = 5/160 = 1/32
r = 1/2
Thus the terms must be
160,80,40,20,10,5
and the sum of the four intermediate means is
150
