Progressions

A Progression is a sequence of numbers which have some kinf of relation. This relation determines what kind of a progression is. Generally, there are two types of progressions:

1. Arithmetic Progression (AP)
2. Geometric Progression (GP)

Any progression (AP or GP) can be generally expressed as

Total Terms:
First Term:
Last Term:

Arithmetic Progression

In AP, the relation amoung sequence of numbers is that the difference between any two successive numbers is same.
Example: 3, 5, 7, 9, 11, 13, ... is an AP with difference 2. This difference is called common difference.

Geometric Progression

In GP, each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio. 

Example: 2, 6, 18, 54, ...
