How to offset transform of each item placed.

This is a section of my code I am using for a 3d inventory system I created. I am stuck on a problem right now about how to offset the transform of each stick placed after the first one. Assume that the first stick is already placed and I would like the next for in this section to be placed next to it by a some variable. This problem is probably easier than I am making but any help is greatly appreciated.

                 if(iStickCount > 1 && iStickCount % 5 != 0)
                 {
                     if(itemPlacedInStack == false)
                     {
                         foreach (Transform child in invSlots[i].transform)
                         {                            
                             int childCount = child.transform.parent.childCount;
 
                             if(childCount < 5)
                             {
                                 if(child.transform.name == "inv_Stick")
                                 {
                                     Vector3 childPos = child.transform.position;
                                     Vector3 transPos = transform.position;
 
                                     transform.parent = invSlots[i].transform;
                                     transPos = childPos;
                                     //transPos.x = childPos.x +1;
                                     itemPlacedInStack = true;
                                     return;
                                 }
                             }
                         }
                     }
                 }
