Oh, dude, halfway between 17 and 63? That's like asking me to pick a favorite child - impossible! But, if you really want to know, it's 40. I mean, I could go into the whole math explanation, but let's be real, who really cares about that stuff anyway?
It can be, only it is not a perfect square. 72 = 7*7 = 49 and 82 = 8*8 = 64 So 63 lies between the squares of 7 and 8 and so there is no whole number whose square is 63.
There isn't a prime number between 63 and 65
