Transform Position, add plus 5

I have this code:

using UnityEngine;

using System.Collections;



public class GunParentScript : MonoBehaviour {

	

	private Camera myCamera;

	private Transform GunTransform;

	

	// Use this for initialization

	void Start () {

		

		if(networkView.isMine == true){

			

			myCamera = Camera.main;

			GunTransform = transform.FindChild("Gun");

			

		}else{

			

			enabled = false;

			

		}

		

		

	}

	

	// Update is called once per frame

	void Update () {

		

		myCamera.transform.position = GunTransform.position;

		myCamera.transform.rotation = GunTransform.rotation;

		

	}

}

But I want the (myCamera.transform.position = GunTransform.position;) → at the update function
to add like 5 to it.

I think this is what the position meanse: 0,0,0 and I wan’t it to be 0,0,5.
Its just a example but that’s it actualy

I tried myCamera.transform.position = GunTransform.position + 5; but that didn’t work.

Thanks Alot!

maybe

 myCamera.transform.position = GunTransform.position + new Vector3(0.0f, 0.0f 5.0f);
