Position of Instantiated Objects from a reference

Hi, I want to instantiate objects with an equal distance from a reference

So for example if my reference is situated in the (0,0,0) and if I have 1 obj, then it’s center will be in the position of the reference.

if i have 2 objects than, the sum of then they will also place themselves auto. according to the reference.

Here is the example

Well just to be very simple …You can make prefab of these 2 , 3 and 4 obj , and instantiate them . Center of all the Objects will be at instantiation position.

I hope this is want u want
