Question

Find harmonic mean between two number 4 and 16

Answer 1

AnswerDear Student,

◆ Answer -

Harmonic mean = 6.4

● Explanation -

Harmonic mean of two numbers x and y is calculated by formula -

H = 2 / (1/x + 1/y)

Rearranging we get,

H = 2xy/(x+y)

Now substitute, x = 4 and y = 16,

H = 2 × 4 × 16 / (4 + 16)

H = 128 / 20

H = 6.4

Therefore, harmonic mean of 4 and 16 is 6.4.

Thanks dear for asking. Hope this helps you...
