If you are using this ajax in a .php file than you should do something like this to your url:

function increase(){
var number = parseInt($('#number').html()) + 1;
var base_url = "";
$.ajax({
    type: 'POST',
    url: base_url+'welcome/increase',
    data: { increase:number },
    success:function(response){
        $('#number').html(response);
    }
  });
}

OR if you are doing this in a .js file than you need to add this line inside your head tag

And than use this :

function increase(){
var number = parseInt($('#number').html()) + 1;
$.ajax({
    type: 'POST',
    url: base_url+'welcome/increase',
    data: { increase:number },
    success:function(response){
        $('#number').html(response);
    }
  });
}

Hope that it resolves the problem. However, its always a good idea when developing in the local environment to set the base_url in config.php like this :

$root = "http://".$_SERVER['HTTP_HOST'];
$root .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
$config['base_url']    = $root;
