Arithmetic Progressions – Class X – Part 1 | Concepts | Exercise 5.1 Solved

An arithmetic progression is a list of numbers in which each term is obtained by adding a fixed number to the preceding term except the first term.

This fixed number is called the common difference of the AP. Remember that it can be positive, negative or zero.

You can see that a, a + d, a + 2d, a + 3d, . . . represents an arithmetic progression where a is the first term and d the common
difference. This is called the general form of an AP.

By looking at the terms of a list of numbers, one can tell that the
difference between any two consecutive terms is same or not. If they are same, it is an AP.
