có tất cả số các số chẵn là:

    2+5=7(số)

có 6 khoảng cách bằng 2.

hiệu 2 số đó là:

    2*6=12

     Đáp số: 12

10 tháng 7 2015

giữa 2 số chẵn có 5 số chẵn thì sẽ có 6 số lẻ 

Vậy hiệu của 2 số đó là:5+6+1=12

chính xác 100%

20 tháng 9 2015

Giữa hai số lẻ có hiệu là 2.

=>hiệu  là: 8 x 2 = 16

Tick đúng nha
