Let G be the geometric mean of two positive numbers a and b, and M be the arithmetic mean of and
if is 4:5 then a:b can be:
As we learnt in
Arithmetic mean of two numbers (AM) -
It is to be noted that the sequence a, A, b, is in AP where, a and b are the two numbers.
Geometric mean of two numbers (GM) -
It is to be noted that a,G,b are in GP and a,b are two non - zero numbers.
Given G2 = ab
