Whether or not you are able to update your iPad to a newer version of iOS/iPadOS will be dictated by the iPad model - and the currently installed version of iOS. You can find this information here:

If your iPad is not capable of update to a more recent version of iPadOS than is currently installed, should you wish to use Apps or services that require a higher version than your iPad is capable, your only option is to replace your iPad with a much newer or current model iPad. An iPad will only be incapable of update if its internal resources (CPU and RAM) are insufficient to support the demands of a newer version of iPadOS. App Developers may only support the current and perhaps one or two prior major versions of iOS/iPadOS due to internal OS dependencies - such as App libraries that may not be supported in earlier versions.
If your iPad is capable of update to a more recent version of iOS/iPadOS than is currently installed, these support pages outline both the available methods by which the update can be performed - and troubleshooting should you experience difficulties:
Update your iPhone, iPad or iPod touch – Apple Support
If you can't update or restore your iPhone, iPad or iPod touch – Apple Support
If your iPhone, iPad or iPod touch won’t update - Apple Support
