x+(x+1)+(x+2)=-144 x+x+1+x+2=-144 3x+3=-144 -3 -3 3x=-147 --- --- 3 3 x= -49 -49, -48, -47
To sum the integers: 1 + 2 + 3 + 4 + 5 + . . . . . + 142 + 143 + 144 = ?The 1st and last: 1 + 144 = 145The 2nd and second-last: 2 + 143 = 145The 3rd and third-last: 3 + 142 = 145The 4th and fourth-last: 4 + 141 = 145The 5th and fifth-last: 5 + 140 = 145There are (144/2) = 72 pairs.Each pair adds to 145.The total is (72 x 145) = 10,440
