Use a figure to show the 3-way handshake to establish a connection in the TCP protocol.

Sure, here's a diagram that shows the 3-way handshake to establish a connection in the TCP protocol:
```
Client Server
| |
| SYN (Sequence=X) |
|---------------------------------------------->|
| |
| SYN (Sequence=Y, Ack=X+1) |
|<----------------------------------------------|
| |
| ACK (Acknowledgement=Y+1, Sequence=X+1) |
|---------------------------------------------->|
| |
| Connection Established |
| |
```
In this diagram, the client initiates the connection by sending a SYN (synchronize) message to the server. The message includes a randomly generated sequence number (X) that the server will use to identify subsequent messages from the client.
The server responds with a SYN-ACK message, which includes its own randomly generated sequence number (Y) and an acknowledgement number that is set to the client's sequence number plus one (X+1).
Finally, the client sends an ACK (acknowledge) message back to the server, which includes an acknowledgement number that is set to the server's sequence number plus one (Y+1).
Once the 3-way handshake is complete, both the client and server have agreed on a sequence number for the connection and are ready to exchange data.
