Defining instantiate as a variable?

Instantiate(prefeb[prefeb_num], teleport[0].position, teleport[tele_num].rotation );

How can I define this instantiate as a variable?

GameObject instantiatedObject = Instantiate(prefeb[prefeb_num], teleport[0].position, teleport[tele_num].rotation ) as GameObject;

Now you have your object as variable of type GameObject.
