Can you use the apple pencil(1st generation) with the iPad air 2?

See the info below for compatible models.

Apple Pencil - Select - Apple

Sorry, no. There is no version of the Apple Pencil compatible with that model.

Your Apple Pencil will only work with iPad Air.

As what i know you can not

No Apple Pencils work with ANY iPads made before late 2015 and this includes the 2014 iPad Air 2.
