Remove space between two objects at runtime

hi all I am new to unity 5 and i am creating a football game with kinect i have created a stadium in which i want to create audience at runtime

Finally The code i m generate for creating audience using UnityEngine; using System.Collections;

public class Audience : MonoBehaviour {

 public GameObject audiance;
 public GameObject audiance1;
 public GameObject audiance2;
 public GameObject audiance3;
 public GameObject audiance4;
 public GameObject audiance5;


 //public float spacing = -1.8f;
 float zSpace = -1.8f;

 int x;
 
 void Start() {
     for (x = -2; x <= 5; x++) 
     {
         createAudiance();
         createAudiance1();
         createAudiance2();
         createAudiance3();
         createAudiance4();
         createAudiance5();

     }

 } 
 // Update is called once per frame
 void Update () {
 
 }
 public void createAudiance()
 {
     //Vector3 pos = new Vector3(x , -4.492f, 8.544f);
     //float temp;
     //temp = audiance.transform.position.x + zSpace;
     Vector3 pos = new Vector3(x, -4.492f,8.544f );
     Instantiate(audiance, pos,Quaternion.Euler(0,-180,0));
 }
 public void createAudiance1()
 {
     Vector3 pos = new Vector3(x, -4.36f, 9.04f);
     Instantiate(audiance1, pos,Quaternion.Euler(0,-180,0));
 }
 public void createAudiance2()
 {
     Vector3 pos = new Vector3(x, -4.186f, 9.309f);
     Instantiate(audiance2, pos,Quaternion.Euler(0,-180,0));
 }
 public void createAudiance3()
 {
     Vector3 pos = new Vector3(x, -4.018f, 9.77f);
     Instantiate(audiance3, pos,Quaternion.Euler(0,-180,0));
 }
 public void createAudiance4()
 {
     Vector3 pos = new Vector3(x, -3.854f, 10.09f);
     Instantiate(audiance4, pos,Quaternion.Euler(0,-180,0));
 }
 public void createAudiance5()
 {
     Vector3 pos = new Vector3(x, -3.692f, 10.53f);
     Instantiate(audiance5, pos,Quaternion.Euler(0,-180,0));
 }

} The above code created my audience but i am unable to remove space between two game object

Plz provide me solution for this Thank You
