How do I get the average X & Y Coordinates between 4 players

Hello, once again I have a question about the camera within the game I'm making. Based on the previous question where I got to use a lerp on my camera and based on that lerp the camera zooms out. (layoutsize).

I had no problems controlling the camera between two players lerp(Camera.X,Player1.X+Player2.X/2,0.3).

But with four players this does not work, does anyone have an idea to center the camera at four players?

Would this example help?

I've been trying to fix the camera for a while now and this deffinitely helped, thanks a lot.
