What x2 and x3 stands for?

So, I don't quite get the diference between a x2 icon and a x3? Is that something about the resolution when creating?

It is! @2x icons are for traditional retina displays, and @3x is for the retina display on the iPhone 6 Plus.

But when doing the icon, how do I know if the resolution is adequate for x2 or for x3?

You'll want to look it up. Depending on if it's an app icon, app artwork, or even a launch screen the needed resolution is different.
