Spacing based on loop index(middle, then right, then left)

Unity Engine
1

I’m not sure the correct term but I’m looking to simply place an object’s position based on the count of the loop.
The spacing here being the X axis.

0: Middle

  1. Right/ + 5f
  2. Left/ - 5f;
  3. Right/ + 10f;
  4. Left /- 10f;

An attempt:

        int loopIndex = 0;
        foreach(EnemyData i in enemiesInCounter){
            int modifier = 5 * loopIndex;
            if(loopIndex % 2==0){
                modifier = -5 * loopIndex;
            }
          Debug.Log(Vector2.right * modifier);
            Vector2 position = Vector2.right * modifier + (Vector2.up * 2.5f);
            SpawnEnemyFromData(i,position);
            loopIndex++;
        }

The problem here is that loop count 2 is set to -10f instead of 5f;

I love this stuff… here’s my off-the-cuff attempt… print it out… I think it’s correct!

for (int i = 0; i < 11; i++)
{
  int index = (i + 1) / 2;
  int sign = (i % 2) * 2 - 1;
  int result = index * 5 * sign;

  Debug.Log( "i = " + i + ", result = " + result);
}

Magic is lines 3 to 5: accepts i and returns result.
