That 2014 tablet probably can’t be updated. Many tablets and phones never get an updated version of Android. My 2014 LG LS620 phone came with, and is stuck with, KitKat.
If you buy the high end Android phones from Google you get two Android updates before they reach the end of update life. e.g. Nexus 5X started with Marshmallow, got Nougat and then finally Oreo.
