Sorry to hear about your issue :(
The ipad's operating system is now corrupted and it is now in recovery mode. We need to restore the ipad to bring it back to functional state.
Do you have a computer with itunes installed? If you do, open itunes in the computer and connect the ipad to the computer. Your ipad will be listed in itunes. Click on it and then click on "restore ipad".
If you don't have itunes installed, you can install it from the following website
Let me know if you find any difficulty.

you don't need to go for subscriptions, that is only optional
