In mathematics, an

**arithmetic progression**(AP) or**arithmetic sequence**is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 … is an arithmetic progression with common difference of 2.
If the initial term of an arithmetic progression is and the common difference of successive members is

*d*, then the*n*th term of the sequence () is given by:

#### C Program to print Arithmetic Progression:

#include <stdio.h> int main() { int i, term, difference, ap; printf("Enter number of terms: "); scanf("%d",&term); printf("Enter the common difference of Arithmatic Progression: "); scanf("%d",&difference); printf("The arithmatic progression from 1 to %d with term difference %d is: \n",term,difference); for(i=1;i<=term;i++){ ap = 1+(i-1)*difference; printf("%d ",ap); } return 0; }
