AP GP of numbers given asked for calculate HP.
Read Solution (Total 2)
-
- f AM, GM and HM be the arithmetic, geometric and harmonic means between a and b, then;
AM=a+b/2
GM=ab^1/2
HM=2ab/a+b
Therefore, we can write:
AM*HM=ab=GM^2
HENCE IN THE GIVEN PROBLEM HM=GM^2/AM - 11 years agoHelpfull: Yes(11) No(0)
- ap=(a+b)/2,gp=sqrt of(ab),hp=(2ab)/(a+b)therefore
hp=gp^2/ap - 11 years agoHelpfull: Yes(1) No(0)
