Question
l, m, n are the pth, qth and rth term of a G.P. all positive, then 
equals
equals Options
A.- 1
B.2
C.1
D.0
Solution
l = ARp - 1 ⇒ log I = log A + (p - 1) log R
m = ARq-1 ⇒ log m = log A + (q - 1) log R
n = ARr-1 ⇒ log n = log A + (r - 1) log R
Now,
m = ARq-1 ⇒ log m = log A + (q - 1) log R
n = ARr-1 ⇒ log n = log A + (r - 1) log R
Now,
