If You Do NOT Have the Apple ID and Password

If you bought a used iPad Air 2 that is still Activation Locked and you cannot contact the previous owner, your options are limited.

A. Official Apple Support Request (Best Alternative)

If you are the legal owner, Apple may be able to remove the lock.

Go to Apple's Activation Lock support request page (search for "Apple Activation Lock support request" on Google).

You will need to provide the iPad's serial number or IMEI/MEID.

You must provide proof of purchase (an original receipt or invoice) that clearly shows the device's serial number and the date of purchase. Apple will not approve requests without valid documentation.

Wait for Apple's verification and removal process.

Here are the Apple support pages that outline the Activation Lock - and the only mechanisms by which it can be satisfied:

As you will discover, unless you are the owner of the AppleID that was last used to activate the device, you’ll not be able to defeat or bypass the Activation Lock. With documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple may be prepared to assist - otherwise they and nobody here will be able to help you.

If you have the necessary documentation, Apple have introduced a portal though which you may be able to request release of an Activation Lock:
