Hello. I forgot my iPad passcode please help

You will need to restore the device using a computer. The process will erase the device. Later you can restore your data from a recent back-up. Instructions in the blue link above your name on this page.

My iPad Pro is not compatible with my MacBook Air and therefore cannot connect both to sort my passcode. How can I sort my passcode without using the laptop

Can you please help

In what sense is your iPad not compatible with your Mac? Age or cable type?

If you cannot use your own Mac, use somebody else's, perhaps ask a nearby Apple Store or computer repair shop to help.
