Harmonic Progression

A Harmonic Progression (HP) is a sequence of numbers where the reciprocals (1 divided by each number) form an arithmetic progression, meaning they increase or decrease by a constant amount. For example, if you take the numbers 1, 1/2, and 1/3, their reciprocals are 1, 2, and 3, which increase by 1. HP is often used in various fields, including music, physics, and finance, to analyze phenomena where rates or ratios are more relevant than absolute values. In essence, it's a way to understand relationships between numbers based on their inverses.
