Average function without overflow exception

Question

.NET Framework 3.5.
I\'m trying to calculate the average of some pretty large numbers.
For instance:

using System;
using System.Linq;

class Program
{
           


        

Answer 1

where an average computation of (a+b)/2 can be replaced with a+((b-a)/2.
