a.S=1-2+3-4+...+99-100

 

  =(1-2)+(3-4)+...+(99-100)

 

  =(-1)+(-1)+...+(-1)

 

Vì từ 1->100 nên có 50 cặp 

 

=> có 50 số -1

 

=>(-1)+(-1)+...+(-1)=-50

 

=>1-2+3-4+...+99-100=-50 

b. n + 5 chia hết cho n - 2

 

n - 2 + 7 chia hết cho n - 2

 

Mà n - 2 chia hết cho n - 2

 

=> 7 chia hết cho n - 2

 

n - 2 thuộc Ư(7) = {-7 ; -1 ; 1 ; 7}

 

n - 2 = -7 => n = -5

 

n - 2 =-1 => N = 1

 

n - 2 = 1 => n = 3

 

n - 2 = 7 => n = 9

 

Vậy n thuộc {-5 ; 1 ; 3 ; 9}

From Nguyen Duc Hien to Luca. I had a fun weekend. My dad took me to the City Center Square. After that, my sister from China went home and gave me a lot of gift! The weather in the weekend is some cloudy and cold. But I like it so much!
