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

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%

la 12 do ban

hiệu 2 số là 

1 * 21 = 21 

số bé 

(2009 - 21) : 2 = 994 

số lớn là 

2009 - 994 = 1015

a) Tổng 2 số là 2009(số lẻ) nên 2 số đó 1 số là chẵn và một số là lẻ.
Giữa 1 số chẵn và 1 số lẻ có 20 số chẵn thì giữa chúng cũng có 20 số lẻ.

Vậy hiệu của chúng là :

     20 + 20 + 1 = 41 ( toán trồng cây)
               Số lớn là:

(2009+41):2= 1025 và số bé là: 2009 - 1025 = 984.

b) Gọi 2 số cần tìm là a và b (a,b là số tự nhiên; a > b)
Vì giữa a và b có 15 số tự nhiên khác

\(\Rightarrow\) a - b =16 (1)
Lại có : a + b = 828 (2)
Cộng vế với vế của (1) và (2) 

\(\Rightarrow\) 2a = 844\(\Rightarrow\) a = 422
\(\Rightarrow\) b = 828 - 422 = 406

Vậy 2 số cần tìm là 422 và 406
