// Use this for initialization

// Update is called once per frame

Hello there,

You do want to use lerp here, but not that way. The third value you pass in should be “t”, a value that increases from 0 to 1, where 0 is the start value and 1 is the target. You can read more about the proper use of Lerps (and all you can do with them) on this page.

Here is an example of basic a implementation in Update that should work for you:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class test : MonoBehaviour
{
    private float t = 0.0f;
    private float speed = 0.1f;

    [SerializeField] private GameObject go_cube1 = null, go_cube2 = null;

    private void Update()
    {
        if (Input.GetKey(KeyCode.RightArrow))
            t += speed * Time.deltaTime;
        else if (Input.GetKey(KeyCode.LeftArrow))
            t -= speed * Time.deltaTime;

        Mathf.Clamp(t, 0.0f, 1.0f);
        transform.position = Vector3.Lerp(go_cube1.transform.position, go_cube2.transform.position, t);
    }
}

Hope that helps!
