a, b, c are in G.P
let r be common ratio
So let
a=m------------------1
b=mr---—-------------2
c=mr^2------------------3
a^1/x=b^1/y=c^1/x
applying log and taking equality to t
1/x loga=1/y logb=1/z logc=t
Putting value
logm=xt--------------4
logm+logr=yt--------5
logm+2logr =zt------6
Solving
(5-4)
U get logr=t(y -x)
Putting in 6 U GET
logm=[z-2(y-x)]t
Putting value of 4 as t=logm /x U get
x=z-2y+2x
Y=Z+X/2
WHICH IS ARITHMATIC MEAN
