**(A) Main Concepts and Results**

- An arithmetic progression (AP) is a list of numbers in which each term is obtained by adding a fixed number d to the preceding term, except the first term a. The fixed number d is called its common difference. The general form of an AP is a, a + d, a + 2d, a + 3d,…
- In the list of numbers a
_{1}, a_{2}, a_{3},… if the differences a_{2}– a_{1}, a_{3}– a_{2}, a_{4}– a_{3},… give the same value, i.e., if a_{k+1}– a_{k}is the same for different values of k, then the given list of numbers is an AP. - The nth term a
_{n}(or the general term) of an AP is a_{n}= a + (n – 1) d, where a is the first term and d is the common difference. Note that a_{1}= a . - The sum S
_{n}of the first n terms of an AP is given by

If l is the last term of an AP of n terms, then the sum of all the terms can also be given by

Sometimes S_{n} is also denoted by S.

- If f S
_{n}is the sum of the first n terms of an AP, then its nth term a_{n}is given by
