Question: Suppose a client (Host A) requests a TCP connection between it and a server (Host B). Host A initiates the communication with a SYN packet

Suppose a client (Host A) requests a TCP connection between it and a server (Host B). Host A initiates the communication with a SYN packet containing the sequence number 1023. When the connection is established Host A sends three segments each with a payload of 128 bytes. Host A receives acknowledgments for the first two segments before its timer times out but the third segment requires a retransmission. What is the sequence number contained in the FIN packet sent by host A upon completion of the data transfer?
