Append a text file using C#

I have write the following C# code to append a file. I need to store each data in a new line. But after entering the data I can see them in a single line.

How can I modify my code to get one input in one line.

static void Main(string[] args)
{

      Console.WriteLine("Please enter the question:");
      string question = Console.ReadLine();
      File.AppendAllText("question.txt", question);
      File.AppendAllText("question.txt", "\n");
      Console.WriteLine("Please enter the term to solve");
      string term = Console.ReadLine();
      File.AppendAllText("question.txt", term);
}

Required output -

x+2=10

x

Output I got - 

x+2=10x

Add + Environment.NewLine after term. You can concat string with +(plus) "mystring" + " another String" + " my last string" = "mystring another String my last string".

static void Main(string[] args)
{

      Console.WriteLine("Please enter the question:");
      string question = Console.ReadLine();
      File.AppendAllText("question.txt", question);
      File.AppendAllText("question.txt", "\n");
      Console.WriteLine("Please enter the term to solve");
      string term = Console.ReadLine();
      File.AppendAllText("question.txt", term + Environment.NewLine);
}

The text viewer you are viewing the resulting file with likely expects a "carriage return"(\r) character with each "newline"(\n) character. Try changing the following line:

File.AppendAllText("question.txt", "\n");

To this:

File.AppendAllText("question.txt", "\r\n");

Why not to build a string and write it at once?

  Console.WriteLine("Please enter the question:");
  string question = Console.ReadLine();

  Console.WriteLine("Please enter the term to solve");

  question += Environment.NewLine + Console.ReadLine();
  File.WriteAllText("question.txt", question );

Anyway, as C# application might be cross platform, /n is not always a character for the new line, that is why it is better to use Environment.NewLine instead
