Match the formulas with the descriptions of the behavior of the sequence as $n\to\infty$.

 1. $s_n = 1 + \cos(n)/n$
 2. $s_n = (n+1)/n$
 3. $s_n = \cos(1/n)$
 4. $s_n = 1 - n^2$
 5. $s_n = 3 + (-1)^n/(n)$

A. converges to one from below
B. converges to one from above and below
C. converges to one from above
D. diverges to $-\infty$
E. converges to three from above and below
