activation lock skip

You cannot “skip” or bypass the Activation Lock. This is security feature that is intended to ensure that lost or stolen devices have no value if appropriated. As is, the iPad is useless to you.

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

Activation Lock for iPhone, iPad, and iPod touch - Apple Support

Turn off Activation Lock – Apple Support

As you will discover, unless you are the owner of the AppleID that was last used to activate the device, or unless you can secure the cooperation of the previous owner, you’ll not be able to defeat or bypass the Activation Lock. Without documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple won’t assist - and nobody here will be able to help you.

The All Too Common SAD Reality of Buying … - Apple Community

You providing a serial number to anyone will make absolutely no difference. The only methods by which an Activation Lock may be resolved have already been described - with appropriate links.
