In a TCP connection, the initial sequence number at the client site is 1846. The client opens the connection, sends only one segment carrying 1200 bytes of data, and closes the connection. What is the value of the sequence number in SYN, DATA and FIN segment sent by the client? 

  1. 1200, 3046, 4246
  2. 1846, 1200, 3046
  3. 1200, 1846, 3046
  4. 1846, 3046, 3046

I may be wrong here please correct me.

when sender will be in syn phase seq no. = 1846, now when sender has to send data it's sequence number = 1847 and while doing fin at termination step sequence number will be 3047.

It's a TCP connection so after handshaking sequence number has to increment by 1.
