Question

If the number of fives in 5+(-5)+(5)+(-5)+(5)+(-5)+...is 251,then the sum is 0. Is this statement true or false?Why?

Answer 1

False statement bcoz when number of five will be odd then sum will be 5
otherwise when it even then sum is 0
As 251 is odd so sum will be 5 not 0

Answer 2

This statement is false.
This is because when the number of times the number added is odd,the answer would be 5.

Hope it helps................
