Question

Find A.M., G.M., H.M. of numbers 4 and 16.
(A.M. = Arithmetic mean, H.M. Harmonic mean and
G.M. = Geometric mean)

Answer 1

Answer:

AM = 10

GM = 8

HP = 6.4

i hope this will help.....

Answer 2

Answer: A.M. = 10, G.M. = 8 and H.M. = 6.4

Step-by-step explanation:

Given two numbers a= 4,   b= 16

A.M. (Arithmetic  mean ) =  $\dfrac{a+b}{2} = \dfrac{4+16}{2} =10$

G.M. (Geometric mean) =  $\sqrt{ab} = \sqrt{4\times 16} =\sqrt{64} =8$

H.M. (harmonic mean) =   $\dfrac{2}{\dfrac{1}{4} +\dfrac{1}{16} } =\dfrac{32}{5} =6.4$

Hence, A.M. = 10, G.M. = 8 and H.M. = 6.4
