An Arithmetic progression is a categorization of numbers in which each number is obtained from its preceding number either by adding or by subtracting a constant number known as the common difference “d”.

Geometric Progression:

A Geometric Progression is an arrangement where each number is obtained by either multiplying or dividing the previous number with a specific number called the common ratio “r”.

Harmonic Progression:

Any series is known to be a Harmonic Progression series when its correlatives are in Arithmetic progression.
