, 16:42, 12 August 2014→Interpretation of the problem
#In this problem 'a' is the arithmetic mean of 'b' and 'c'
#In this problem 'a' is the arithmetic mean of 'b' and 'c'
#They also given that 'b' is the geometric mean of 'a' and 'c'
#They also given that 'b' is the geometric mean of 'a' and 'c'
==What is asked of student==
#In this problem we prove that 'c' will be the harmonic mean between 'a' and 'b'
#That is we just show that c = <math>\frac{2ab} {a + b}</math>
