We can do this problem by another method also. See the sequence. If you remove 100 then you can see continuous even odd sequence.
8=even.
27=odd.
64=even.
125=odd.
216=even.
343=odd.
If you see that there will continuous even, odd sequence. Since 100 comes next to 64. Definitely it is an wrong no. |
