Nhận xét :

Đầu dãy số của Mèo Tom : 1 ; 2 ; 3 ; 4 ; 5....

Đầu dãy số của Jerry : 41 ; 42 ; 43 ; 44 ; 45; ...

Đều là những cặp có hiệu là 40.

Vậy để 2 số mà không số nào có hiệu là 40 thì nếu Mèo Tom chọn 20 số đầu thì Jerry chọn 20 số cuối hoặc xen kẽ hoặc ngược lại.

Tổng là : 1 + 2 + 3 + ...+ 20 + 61 + 62 + 63 +...+ 80

= (1+20) x 20 : 2 + (61+80)x20 : 2 = 1620

  Hok tốt !
