Whats the smallest number ("the magic number") that can satisfy these conditions?

 Submitted by Victor Zapana Rating: 3.3333 (9 votes) Solution: (Hide) 53. At first, many have thought it was 37. However, as people have pointed out, 3 + 7 = 10 /2 = 5, which is not even. I am sorry if the "even" is subject to misinterpretation, and next time (if I do have a next time) I won't just write even, but with an added note liek "even whole..." or "even (as in a number divisible by 2)" or something. And wow... I agree with Jer. This "easy" question did spark some discussion. One more point: Bravo to Charlie to be first to supply the answer, and to DJ to smooth all discussions out
