số lớn là 89 

số bé là 22

tk mk nhé mk bị âm nhiều điểm lắm

Số lớn là:   (111 + 67) : 2 = 89

Số bé là:     111 - 89 = 22

Đặt S=1.2+2.3+.........+2011.2012

3S=1.2.3+2.3.(4-1)+...........+2011.2012.(2013-2010)

3S=1.2.3+2.3.4-1.2.3+...........+2011.2012.2013-2010.2011.2012

3S=2011.2012.2013

S=2011.2012.2013:3

S=2714954572

Đặt A = 1.2 + 2.3 + 3.4 + ... + 2011.2012

=> 3A = 1.2.3 + 2.3.3 + 3.4.3 + ... + 2011.2012.3

=> 3A = 1.2.(3 - 0) + 2.3.(4 - 1) + 3.4.(5 - 2) + ... + 2011.2012.(2013 - 2010)

=> 3A = 1.2.3 - 0 + 2.3.4 - 1.2.3 + 3.4.5 - 2.3.4 + ... + 2011.2012.2013 - 2010.2011.2012

=> 3A = 2011.2012.2013

=> A = \(\frac{2011.2012.2013}{3}=2714954572\).
