Is this an arithmetic progression?
Given 3 numbers
a, b, and c your task is to determine if those 3 numbers could form an arithmetic progression. Print arithmetic progression in case those 3 numbers could be part of an arithmetic progression and no pattern found otherwise.Definition of an Arithmetic Progression
An arithmetic progression is a sequence of numbers where each term is obtained by adding a fixed number to the previous term. For example, -4, -2, 0, 2, 4 is an arithmetic progression because each term is obtained by adding 2 to the previous term (-4 + 2 = -2, -2 + 2 = 0, and so on).
