Question

Write the program to find the sum of the following series:

S = (a + 1) + (a + 2) + (a + 3) + ............... + (a + n)

Answer 1

import java.util.*;
public class Q3b
{public static void main(String args[])
{int a, n, cnt = 1, term, sum = 0;
Scanner obj = new Scanner(System.in);
System.out.println("Enter the value of a");
a = obj.nextInt();
System.out.println("Enter the value of n");
n = obj.nextInt();
for (int i = 1; i <= n; i++)
{term = a + i;
sum = sum + term;
}
System.out.println("Sum of the series = " + sum);
}}
