Host A and $B$ are communicating over a TCP connection, and Host $B$ has already received from A all bytes up through byte $213.$ Suppose Host A then sends two segments to Host B back$-$to$-$back. The first and second segments contain $35$ and $50$ bytes of data, respectively. In the first segment, the sequence number is $214,$ the source port number is $340,$ and the destination port number is $80.$ Host B sends an acknowledgment whenever it receives a segment from Host $A.$

a$.$ In the second segment sent from Host $A$ to $B,$ what are the sequence number, source port number, and destination port number?
