Question

If the pth, qth & rth term of a G.P. are x,y,z then (q-r).logx+(r-p) log y +(p-q)log z
​

Answer 1

Step-by-step explanation:

Let first ratio of GP be a

and common ratio of G.P be r

Tp = ar^(p-1) = x

logx=loga+(p−1)logr

Multiply by q−r, r−p and p−q and add we get,

(q−r)logx+(r−p)logy+(p−q)logz=0
