I have a Macbook Pro from mid-2015 and want to extend the display onto my iPad Pro 2nd generation, is there any possibility to do so? Any App-Recommendations?

Sidecar - Apple Support

leroydouglas' solution is perfect if you are running Catalina on the Mac. I think iOS 13 is required for the iPad but I could be wrong. Another solution (which isn't free) is Duet which can be purchased at the App store.
