Consider the program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    
    class Program
    {
        static void Main(string[] args)
        {
            int a = 0;
            int b = 1;
            int c = 0;
            int i = 0;

            Console.Write(a + ", " + b );

            for (i = 1; i < 10; i++)
            {
                c = a + b;
                Console.Write(", "+c);

                a = b;
                b = c;
            }

            Console.WriteLine();

        }
    }
}

Output

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55

In this program, we are taking two integer numbers 0 and 1 initially, program will add them and print third element as 1 (which is sum of 0 and 1) and then program will sum last two elements and print next element 2 (which is sum of 1 and 1) and so on… Here we are printing fibonacci series till 10 terms (10 elements).
