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}
