@[Removed] It's true the route is not on the table, so it will send to the default gateway via 172.16.2.2. When you calculate the subnetmask of 172.16.2.2 in the routing table, then you will see that it's 255.255.254.0. The reason is because we are working with the 172.16.2.0/23 network because that's the range it fell into.
