how do I interpret the minor version in this command?

In the 4.1 lab on page 4 it says:

"Replace the apt repository definition so that apt points to the new repository instead of the Google-hosted repository. Make sure to replace the Kubernetes minor version in the command below with the minor version that you are going to upgrade."

student@cp: ̃$ sudo sed -i' s/29/30/g' /etc/apt/sources.list.d/kubernetes.list

meanwhile, when I check the minor version with kubectl version, it shows "v1.29.1". 29 being the minor version, how to I replace the minor version in the printed command to reflect that?
