Let me chime in and provide additional information about the invoice numbering system in QuickBooks Desktop, hedy. I'm here to guide you and ensure you can go back to your preferred sequence so you can create new invoices. 

The invoice number sequence changes only when digits are manually entered. QuickBooks generates the number based on the last numeral entered. In this case, I recommend entering the preferred Invoice # 3562797 so the system will automatically populate the numerical sequence. You can refer to the image attached below for visual reference. 

Afterward, when you create a new invoice, it will follow the order you set up previously. 

Moreover, you can read this article to help you in recording your sales and keep track of your products and services in QuickBooks: Create an invoice in QuickBooks Desktop. 

If you have additional questions or need further help managing your invoices or sales transactions, let me know in the comments, hedy. I'd be happy to provide continued assistance. I'm committed to providing you with the information you need to optimize your QuickBooks experience and achieve your business goals.
