In the case of Fibonacci series, the next number is the sum of the previous two numbers for example 0, 1, 1, 2, 3, 5, 8, 13, 21 etc. The first two numbers of Fibonacci series are 0 and 1. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {             int val1 = 0, val2 = 1, val3, i, number;             Console.WriteLine("Please Enter any number");             number = int.Parse(Console.ReadLine());             Console.WriteLine(val1 + " " + val2);             for (i=2;i<=number;i++)             {                 val3 =...

Prime number is a number that is greater than 1 and divided by 1 or itself. In other words, prime numbers can't be divided by other numbers than itself or 1. For example 2, 3, 5, 7, 11, 13, 17, 19, 23.... are the prime numbers. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {             int number, i, m = 0, flag = 0;             Console.WriteLine("PLEASE ENTER THE NUMBER TO CHECK PRIME NUMBER");             number = int.Parse(Console.ReadLine());             m = number / 2;             for(i=2;i<=m;i++)             {           ...
