TCP Sequence Number

Tags: Networking

I have a confussion about TCP Sequence Numbers.
If, for example a client starts a conection, send 1 package and ends it, what would be the SN for the SYN, Data and FIN segments.
I am not sure if the answer wold be 0, 2 and 3.
Does the sequence number change due to the three way handshake?
(Let’s say that the initial SN is 0 and the MSS is 1000 bytes.)

Thanks in advance!
