The sum is the middle binomial coefficient
	( 2n )
	(  n )

I don't think you mean n is "any real number"; rather, this is for
n  any natural number. That's your clue that this question isn't
numerical analysis at all but rather number theory (or combinatorics);
sci.math  would have been a better choice.
