Every time a value becomes a defined amount more than it's previous value

I was wondering what's the easiest way of writing an if statement to find when my intiger `var a` becomes 5 more than it's previous value?

    function Update () {
        passed = temps + threshold;
        if(Input.GetMouseButton(0)){
            temps += 1 * Time.deltaTime;
        }
    }

    function LateUpdate(){
        if (Input.GetMouseButtonUp(0) && CheckIntPassedLimit()){
        //Do Something
        }
    }

    function CheckIntPassedLimit() : boolean{
        return (temps > passed);
    }

int threshold = 5;
int myInt = 32;
int limit;

void Start()
{
    limit = myInt + threshold;
}

bool CheckIntPassedLimit()
{
    return (myInt > limit);
}

void MyMethod()
{
    if (CheckIntPassedLimit())
    {
        // int has passed the set limit
    }
}
