Bounty: 50

enter image description here

In the Figure 24.13 of Data Communications and Networking, 5/e the first ACK message from the server holds y-1 in it’s Sequence no. field. Note that the first FIN message from the client message had y in it’s Acknowledgement no. field. So shouldn’t the first ACK message from the server be holding y in it’s Sequence no. field instead of holding y-1? Is the diagram faulty or is there a reason behind it?
