C program to find nth term using Arithmetic progrssion

C program to find nth term in given terms. Use Arithmetic progrssion in the program.

An arithmetic progression is a sequence of numbers.
Arithmetic progression,
an = a1+(n-1)*d
an = the nᵗʰ term in the sequence
a1 = the first term in the sequence
d = the common difference between terms

/* C program to find nth term using
*Arithmetic progrssion
*/
#include <stdio.h>

int main()
{
    int an, a1, n, d;
    //3 7 11 15 19 23
    a1 = 3; // First term
    n = 6; // Number of terms
    d = 4; //7-3
    /*Formula of arithmetic progrssion
    *an = a1+(n-1)d
    *an -> nth term
    *a1 -> first term
    *n -> Number of terms
    *d -> Difference of terms
    */
    an = a1+(n1)*d;
    printf(“nth term is =%d”,an);
    

    return 0;
}
Output:
nth term is =23
