Question

The harmonic mean between 2 ans 4 ​

Answer 1

Step-by-step explanation:

a1=2,a2=4. ∴ H.M.=21+412 =32×4 =38 So, Harmonic mean between 2 and 4=38

Answer 2

Step-by-step explanation:

Harmonic Mean is one of the several kinds of average. Mathematically, the harmonic mean between two numbers a and b is defined as. H = 2/ (1/a + 1/b) This can further be written as: H = 2ab/(a+b)

Harmonic mean = n / (∑1/x_i) Where: n – the number of the values in a dataset.
