  {
    int i, j, k = 1, num;
    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the no. of rows: ");
    num = sc.nextInt();

    for (i = 1; i <= num; i++)
    {
      for (j = 1; j <= i; j++)
      {
        System.out.print(k + " ");
        k = k + 2;
      }

      System.out.print("\n");
    }
  }
