Arithmetic progression is the sequence of numbers in which the difference of two consecutive numbers is a constant. Arithmetic progression (AP) is calculated using the formula given below with the common difference, first and last term of a series of numbers.
a - the first term in the series,
n - last term in the series and
d - Common difference.
Arithmetic progression is used in our daily life. If you have equal monthly increments, then the final paycheck of each month is an AP.
