What would happen if packet 4 in this trace was lost?

Hey everyone. I am learning on my own right now about TCP and SMTP. Here is a trace I generated https://www.cloudshark.org/captures/d37a26bda955.
The first three packets are for a TCP handshake. The 4th packet is a data packet sent from the server to the client. What would the next two packets be if this packet 4 were to be lost?
My current guess is that the server would resend the packet with the EXACT same payload, ACK, and SEQ, and then the client would just acknowledge that as usual.
Am I correct, or am I missing something special here?
Thanks!
