Harmonic Progression

A Harmonic Progression (H.P.) is a mathematical sequence generated by taking the reciprocals of an Arithmetic Progression. In this sequence, each term is the harmonic mean of its adjacent terms, this series is called Harmonic Progression.

A Harmonic Progression of separate unit fractions cannot add to an integer (unless in the specific case where (a = 1 and d = 0). The reason lies in the fact that the progression will contain at least one denominator divisible by a prime number that does not a divisor of any other denominator. Harmonic Progression is also called Harmonic Sequence.

In this article, we will discuss the definition, applications, and formula of Harmonic Progression, and understand the difference and relation between arithmetic mean, geometric mean, and harmonic mean to calculate Harmonic Progression in mathematics.

What is Harmonic Progression (HP)?

The Harmonic Progression is derived by taking the reciprocals of the terms in an Arithmetic Progression. If the Arithmetic Progression is represented by the terms a, a + d, a + 2d, a + 3d, and so on, then the corresponding terms in the Harmonic Progression (or Harmonic sequence) are 1/a, 1/(a + d), 1/(a + 2d), 1/(a + 3d), 1/(a + 4d), and so forth up to 1/(a + (n – 1)d). In this context, ‘a’ stands for the initial term and ‘d’ is the common difference, both of which are non-zero values....
