The latest version is iOS 6.1, so if you attempt an upgrade, this is what it will upgrade to. You can go to Settings -> General -> Software Update to update your iPad. If that does not show the update being available, you can connect the iPad to your computer, open iTunes and try to upgrade from there. If it tells you there are no upgrades available, look at the info for your iPad in iTunes and it will tell you what version is currently installed. If it says 6.1, then you are already updated to the latest.
