Which of following statements about the sequence is true?
(Help: A sequence is bounded below if all its terms are greater than or equal to a real number , which is called the lower bound of the sequence. Similarly, a sequence is bounded above if all its terms are less than or equal to a real number , which is called the upper bound of the sequence.)
one of lower bounds is , one of upper bounds is
one of lower bounds is , upper bound does not exist
lower bound does not exist, one of upper bounds is
there exists neither lower bound nor upper bound
