5 + (– 5) + 5 + (– 5) + 5 ......
= (5 – 5) + (5 – 5) + 5........
= 0 + 0 + 0 + 0 + 5......
= 5
Number of 5 in [5 + (– 5) + 5 + (– 5) + 5] is five.
AND five is an odd number.
and it's soluction is 5.
5 + (– 5) + 5 + (– 5) + 5 + (- 5) ......
= (5 – 5) + (5 – 5) + (5 – 5).......
= 0
Number of 5 in [5 + (– 5) + 5 + (– 5) + 5 + (- 5)] is Six.
