Which of following statements about the sequence \( \left( \frac{n+3}{2n}\right)^{\infty}_{n=1} \) is true?
\[\]
(Help: A sequence is bounded below if all its terms are greater than or equal to a real number \(L\), 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 \(U\), which is called the upper bound of the sequence.)
one of lower bounds is \(\frac12\), one of upper bounds is \(2\)
one of lower bounds is \(\frac12\), upper bound does not exist
lower bound does not exist, one of upper bounds is \(2\)
there exists neither lower bound nor upper bound
