51. Just add two to an odd number to work out the next ;)
NeitherExplanation : 0.5 in a fraction is 1/2, so the even number next to it is 0, and the odd number next to it is 1, so those two numbers make 0.5 an odd and even number.

Answer 2 Think about it. Assume that 1 is the odd number you are adding to an even number. Adding it will take you to the next number - which must be an odd number. If you add it to that number, it will take you to the next number, which now is an even number. If you use a number larger than 1 the principal is still the same.
