Chúc bạn học tốt
Tổng hai số lúc đầu là:
2011 x 2 = 4022
Tổng hai số sau khi số thứ nhất tăng gấp đôi là:
3014 x 2 = 6028
Số thứ nhất là:
6028 - 4022 = 2006
Số thứ hai là:
4022 - 2006 = 2016
Đáp số: 2016

Tổng hai số là:45*2=90
Số thứ hai là:12*3=36
Số thứ nhất là:90-36-12=42
trung bình cộng 5 số tự nhiên liên tiếp là số ở giữa. Vậy suy ra dãy số đó là : 109; 110; 111; 112; 113 nha bạn. Kết bạn mình nhoa
Gọi x là số thứ nhất ( Điều kiện X \(\in\) N* )
Số thứ hai là x + 468
Trung bình cộng của 2 số là ( x + x +468 ) : 2 = 1000
\(\Leftrightarrow\)x + x + 468 = 2000
\(\Leftrightarrow\)2x = 2000 -468
\(\Leftrightarrow\)2x = 1532
\(\Leftrightarrow\)x = \(\frac{1532}{2}\)= 766 ( thỏa điều kiện )
Vậy số thứ nhất là 766
Số thứ 2 là 766 + 468 = 1234
