Try using HTML helpers.

@HTML.ActionLink(ans, "GoToAnswer", "ControllerName", new { number = ans })

If number is not in your routing, you should name the parameter:

<a href="/Dashboard/GoToAnswer?number=@ans/">@ans</a>

If it were in your routing, you wouldn't use the query string:

<a href="/Dashboard/GoToAnswer/@ans/">@ans</a>

When you use query string you need to specify the name of the parameter like name=value (as it's a key-value dictionary, so you cannot omit the parameter's name).

You need to change you link to this: 

@foreach (int ans in Model.UnAnsweredList)
{
    <a href="/Dashboard/GoToAnswer?number=@ans">@ans</a>
}

But in fact, you should better use an Html.ActionLink method as your custom routes will be applied:

@foreach (int ans in Model.UnAnsweredList)
{
    @Html.ActionLink(ans, "GotToAnswer", "DashBoard", new {number=ans})
}
