Expands a recurring pattern within a number.

    Args:
        number(tuple): the number to process in the form:
            (int, int, int, ... ".", ... , int int int)
        repeat: the number of times to expand the pattern.

    Returns:
        The original number with recurring pattern expanded.

    Example:
        >>> expand_recurring((1, ".", 0, "[", 9, "]"), repeat=3)
        (1, '.', 0, 9, 9, 9, 9)
