Place GameObjects with even horizontal distribution

I'm looking to place an arbitrary number of GameObjects evenly across an arbitrary width. I've got something close but it isn't quite right.

Code (csharp):

1.  
2.             float newSpacing = rowWidth / (numberOfBlocks + 1);
3.  
4.             for (int i = 0; i < numberOfBlocks; i++)
5.             {
6.                     GameObject newBlock = (GameObject)Instantiate(blockTemplate, this.gameObject.transform.position, Quaternion.identity);
7.                     newBlock.transform.parent = this.gameObject.transform;
8.  
9.                     float newXPosition = (rowWidth / 2) - (newSpacing * i) - this.gameObject.transform.localScale.x;
10.                     newBlock.transform.localPosition = new Vector3(newXPosition, 0, 0);
11.             }
12.  

What I am attempting there is to first calculate the spacing based on the number of objects I want and the overall width, then place the objects accordingly. I'm finding that while they are spaced evenly, but they're not centered inside the expected width. What am I missing?

 

I think the issue is that the center point of blockTemplate. you need to know the width of this object. and add half it's width to the x position.

attach a screen shot so we can see what it's doing wrong

 

In addition to the previous poster's feedback, an observation I made is that you are subtracting localScale.x and I don't think that that applicable here. Since localScale is a proportional value..In closing, I believe your scenario wouldn't need to factor the scaling at all, at first glance.
