The HPA is implemented as a K8s API resource and a controller. The HPA controller periodically adjusts the number of replicas in a scaling target to match the observed average resource utilization to the target specified by the user. While the HPA scaling process is automatic, you can also help account for predictable load fluctuations …

My understanding is that in Kubernetes, when using the Horizontal Pod Autoscaler, if the targetCPUUtilizationPercentage field is set to 50%, and the average CPU utilization across all the pod's replicas is above that value, the HPA will create more replicas. Once the average CPU drops below 50% for some time, it will lower the number of replicas.
