# Arithmetic Progression Definition

In mathematics, an AP or **Arithmetic Progression** is defined as a **sequence of numbers** in which **every number differs by adding or subtracting the same value between them**.

Or, in other words, a **sequence **in which the **difference between each consecutive value is constant** called the **arithmetic progression** or arithmetic sequence. For instance, 2,4,6,8,10 ... is an arithmetic progression because the difference between every number is a constant value "2".

Let us have another example of arithmetic progression; 16,12,8,4,0. Here "-4" is a constant value in this sequence. For a more precise understanding of a concept, let's have a look at the image listed below:
