What version is the iPad mini?

That is a first Generation iPad Mini

Mac iOS version is 9.3.5 (Wifi only) or 9.3.6 if wifi + Cellular.

However, posting serial numbers here is considered a security risk. I've asked the Hosts to edit it out.

Hello,

It is never a good idea to post your device’s serial number on these public forums.

You can view your iPad’s model number in Settings > General > About.
