 transform.position - Vector3.Lerp(transform.position, newPosition, Time.deltaTime*2f);

That line is not a valid statement. You are subtracting 2 vectors but not doing anything with the result and that's why it doesn't make sense.

Depending on what you wanted to do, I guess it should be

 transform.position = transform.position - Vector3.Lerp(transform.position, newPosition, Time.deltaTime*2f);
 
 Which would be the same as 
 
 transform.position -= Vector3.Lerp(transform.position, newPosition, Time.deltaTime*2f);
