We re starting C Programming Tutorial Series.We will try to satisfy our readers by giving some quality content in this series.

To Begin-with we have chosen to start with mathematical series.First series that always troubles students is Arithmetic Progression.In this post you will find some basic idea and some useful concepts below.

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)
