(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 a₁ , a₂ , a₃ ,… if the differences a₂ – a₁ , a₃ – a₂ , a₄ – a₃ ,…  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 a₁ = 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
