Pictorial Presentation:

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise15 {

   public static void main(String[] args)

{
   int i,n,sum=0;

   System.out.print("Input number of terms is: ");
{
   Scanner in = new Scanner(System.in);
		    n = in.nextInt();
  System.out.println ("\nThe odd numbers are :");
   for(i=1;i<=n;i++)

   {
     System.out.println (2*i-1);
     sum+=2*i-1;
   }
   System.out.println ("The Sum of odd Natural Number upto " +n+" terms is: " +sum);

}
}
}

Sample Output:

Input number of terms is: 5                                                                                   
The odd numbers are :                                                                                         
1                                                                                                       
3                                                                                                       
5                                                                                                       
7                                                                                                       
9                                                                                                       
The Sum of odd Natural Number upto 5 terms is: 25
