Arithmetic Progression / Sequence  Mathematically Explained:

Arithmetic progression (AP) is a sequence of numbers in which each term after the first is obtained by adding a constant, d to the preceding term. The constant d is called common difference.

An arithmetic progression is given by a, (a + d), (a + 2d), (a + 3d), ...
where a = the first term , d = the common difference

Sum of first N Terms of AP:

Nth term of an arithmetic progression Tn = a + (n – 1)d
(where Tn = nth term, a= the first term , d= common difference)

Number of terms of an arithmetic progression
n=(l−a)d+1
(where n = number of terms, a= the first term , l = last term, d= common difference)
