*AP - Arithmetic Progression Calculator* is an online tool used to calculate the Sum of n terms of an Arithmetic Sequence and to find out the nth term of the arithmetic. A Progression is the succession of numbers formed and arranged in a definite order according to the certain definite rule. Whereas If each term of a progression differ from its preceding term by a constant, then such a progression is called an arithmetic progression and the constant different is called the common difference of the AP denoted by d. An AP with first term a and common difference d is give by

**a, (a + d), (a + 2d), ...**

The nth term of the Arithmetic Progression can be derived from the formula

Where

T_{n} denotes the value of last term

d denotes the common difference of AP

a denotes the first term of the AP

The Sum of n terms of an arithmetic sequence can be derived from the formula

Where

n denotes the total number of terms. When it comes to online calculation, this arithmetic progression calculator can assist you to calculate the nth term and sum of n terms of an AP
