Answer»

HP means Harmonic Progression.

The first ten members of the harmonic sequence {\displaystyle a_{n}={\tfrac {1}{n}}} {\displaystyle a_{n}={\tfrac {1}{n}}}.In mathematics, a harmonic progression (or harmonic sequence) is a progression formed by taking the reciprocals of an arithmetic progression. if a, a+d, a+2d, ….. is an A.P. then 1/a, 1/(a+d), 1/(a+2d), …… is an H.P.

Equivalently, a sequence is a harmonic progression when each term is the harmonic mean of the neighboring terms.
