Series Pattern Program in Java | sum of series | Pyapiras

In this program you`ll learn to display how to print series pattern program like 1.5 + 2.5 + 3.5 + ...+n

Source Code:

1. public class SeriesProgramPart3 {
2. public static void main(String[] args) {
3. 
   
4. try (Scanner var = new Scanner(System.in)) {
5. double i,n,sum = 0;
6. System.out.println("Enter the number:");
7. n = var.nextDouble();
9. for(i=1.5;i<=n;i++) {
10. sum = sum +i;
11. System.out.print(i+" + ");
12. }
13. System.out.println("\nThe Summation if series is-"+sum);
14. }
16. }
17. 
    
18. }

Output:

Enter the number:

5

1.5 + 2.5 + 3.5 + 4.5 + 

The Summation if series is-12.0

Enter the number:

10

1.5 + 2.5 + 3.5 + 4.5 + 5.5 + 6.5 + 7.5 + 8.5 + 9.5 + 

The Summation if series is-49.5
