## Sum of Harmonic Progression | HP Series

Here you will learn what is harmonic progression (hp) and sum of harmonic progression (hp series). Let’s begin – Sum of Harmonic Progression A sequence is said to be in H.P. if the reciprocal of its terms are in A.P. If the sequence $$a_1$$ + $$a_2$$ + $$a_3$$ + ……… + $$a_n$$ is an HP …
