# Harmonic Progression (H.P)

If reciprocal of each term of a progression are in A.P., then the progression is called Harmonic progression.

The standard form of a H.P. is

**General Term of a H.P.**

General term or

*n*^{th }term of a H.P. is given byT

*=*_{n}**Harmonic Mean**

If H.M. between two given quantities a and

*b*be H, then*a*, H,*b*, are in H.P. thenH =
