    −2+(−4)+6+8+(−10)+(−12)+……


    =[(−2)+(−4)+6+8]+[(−10)+(−12)+14+16]+…………………………….+(−98)+(−100)

    =8+8+……………………………….+(−98)+(−100)
    =8.6+(−98)+(−100)
    =48+(-98)+(-100)
    =(-50)+(-100)
     

  2. −2+(−4)+6+8+(−10)+(−12)+…………………………..+(−98)+(−100)
    =[(−2)+(−4)+6+8]+[(−10)+(−12)+14+16]+…………………………….+(−98)+(−100)
