• ☞ 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.

____________________✍

• ☞ The fixed number is called the COMMON DIFFERENCE of the AP.

• ☞ Common difference is denoted by ‘d’

• ☞ Common difference can be positive, negative or zero.
