I did it like this is this correct?

You have mentioned wrong number of packets in the first line.

How?? i have entered all the three packets of two sets of tcp connection establishment

You have entered wrong number of packets in this file “packet_numbers_for_tcp_connection_setup”

packets of only one set is to be entered or both?

You were on the right track. Enter the 3 packet numbers for one handshake.
The filename packet_numbers_for_tcp_connection_setup has a space at the beginning, please rename this file and submit.
