Yes, please remember to show your code. If you are using the workspaces, you you can use the snapshot function in the workspace and provide the link to that.

In order to find an average of anything you just have to divide the total sum of numbers by the number of numbers

So it would be something like this:

            string entry;
            double sum = 0.0;
            int count = 0;

            while (true)
            {
                Console.Write("Enter numbers to find their average, type \"done\" to finish: ");

                entry = Console.ReadLine();

                if (entry.ToLower() == "done")
                {
                    if (count > 0)
                    {
                        Console.WriteLine("The average is: " + sum / count);
                        break;
                    }
                    else
                    {
                        Console.WriteLine("Nothing to average");
                        break;
                    }

                }

                sum += double.Parse(entry);
                count++;
            }

You'd have to add some checking to guarantee the person types valid numbers and whatnot, also you can add in some flair by changing the input message so like "Now type the second number", then "third number" and so forth.

But you can figure how to do that by yourself :)
