WebAn AP generally is shown as follows: a 1, a 2, a 3, . . . It involves the following terminology. First Term of Arithmetic Progression: As the name suggests, the first term of an AP is the first number of the progression. It is usually represented by a 1 (or) a. WebFinding the sequence: Given a 1, a 2, a 3, …, a n is the sequence in A.P. Then the common difference ' d ' in A.P. is defined as, ⇒ d = a 2 - a 1 = a 4 - a 3 = ⋯ = a 2 n - a 2 n - 1.
