Istantiate object between two vectors

Unity Engine

I would instantiate gameobjects between a Transform and the other. On the X axis, it works. How can I do for Y?

public Transform t1, t2, node;
    public int division;
   void Start ()
    {
        float dist = Vector3.Distance(t1.position, t2.position);
        Vector3 direction = (t2.position - t1.position).normalized;
        Debug.Log(direction.y);
        for (int i = 0; i < division; i++)

        {
            float result = (dist / division) * i;
            Transform t = Instantiate(node, new Vector3(result,result +(direction.y),direction.z),Quaternion.identity) as Transform;
        
        }
   }

Solved thanks!
