How to add 5 more numbers to the existing number

I'm trying to add 5 more numbers to the number that the user puts in but it only goes up to 5. For example if I put 2 it should add 5 more numbers to it so the output should look like this 2 3 4 5 6

function myFunction() {
  var getDiv = document.getElementById("mydiv");
  var input = document.getElementById("test").value;
  if (!isNaN(input)) {
    parseInt(input);
    for (var i = input; i <= 5; i++) {
      getDiv.innerHTML += i;
    }
  } else {
    getDiv.innerHTML += input + " is not a number!!<br />";
  }
}

Try this, which adds input = parseInt(input); to make input a number, and alters your loop to a range of 5.

function myFunction() {
 var getDiv = document.getElementById("mydiv");
 var input = document.getElementById("test").value;
  if (!isNaN(input)) {
    input = parseInt(input);
    for (var i = input; i < input + 5; i++) {
      getDiv.innerHTML += i + ' ';
    }
  } else {
    getDiv.innerHTML += input + " is not a number!!<br />";
  }
}
<div id="mydiv"></div>
<input id="test"></input>
<button onclick="myFunction();">Click me</button>

You can loop from 0 to 4 both included and add that each time to the input value, note that you should cast the string input, so parseInt(input); should be input = parseInt(input); because if you don't update input to a number then it will stay the same string and adding a number to astring just concatenate it so "30" + 5 = "305" and the loop will run for that number!

function myFunction() {
 var getDiv = document.getElementById("mydiv");
 var input = document.getElementById("test").value;
  if (!isNaN(input)) {
    input = parseInt(input);
    for (var i = 0; i < 5; i++) {
      getDiv.innerHTML += i + input;
    }
  } else {
    getDiv.innerHTML += input + " is not a number!!<br />";
  }
}
<div id="mydiv"></div>
<input id="test"></input>
<button onclick="myFunction();">Click me</button>
