Question

find the harmonic mean of 1,1/2,1/3,1/4,1/5​

Answer 1

Answer:

The harmonic mean (H) of n numbers ( x1, x2, x3, ... , xn ), also called subcontrary mean, is given by the formula below.

Harmonic mean

If n is the number of numbers, it is found by dividing the number of numbers by the reciprocal of each number.

Suppose there are two numbers.

H =

2

1/x1 + 1/x2

Suppose there are 3 numbers.

H =

3

1/x1 + 1/x2 + 1/x3
