Do not have a passcode for my iPad. iPhone and MacBook Pro are open and available. Can I use one of them to get new passcode for ipad

A forgotten password cannot be recovered or reset in situ. Unless the passcode is remembered, any locally stored data is now lost - although you will be able to restore your iCloud or iTunes backup to your iPad.

If your iPad is disabled, or you have forgotten your iPad passcode, you have no alternative other than to follow this process:

If you’ve forgotten the passcode on your iPad, or your iPad is disabled – Apple Support

You’ll need access to either a PC (with iTunes installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS). Use of a PC/Mac is unavoidable.

You’ll also need your AppleID and associated password. If these have also been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to one of the following:

• Your primary email address mailbox that corresponds with your AppleID
• Any of the secondary/recovery email addresses that should be configured for your AppleID account
• Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID

Unless you AppleID account has not been fully/correctly configured, or has been seriously neglected, recovery of the AppleID and password should not be difficult.

When you recover access to your credentials, you would be well advised to log-in to your AppleID account from a web browser - and verify/update any email addresses and trusted telephone numbers:
