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:
