Question

Your employer is opening a new location, and the IT director has assigned you the task of calculating the subnet numbers for the new LAN. You've determined that you need 50 subnets for the network beginning with the network ID 172.20.0.0.
PLEASE HELP EXPLAIN HOW THE ANSWER WERE ACHIEVED
I already have the correct answer, but I dont understand how the answer was achieved. Can someone please explain how these values were formed? Why is there a separation of .4 .8 12 in each subnetwork address? why is it from 172.20.0.1 to 172.20.3.254 only when creating 4 subnetworks? the next being 172.20.4.1 to 172.20.7.254 ? I could not understand why
new subnet mask : 255.255.252.0 /22
