You appear to be on a device with a "narrow" screen width (i.e. you are probably on a mobile phone). Due to the nature of the mathematics on this site it is best viewed in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device (you should be able to scroll/swipe to see them) and some of the menu items will be cut off due to the narrow screen width.

Section 10.2 : More on Sequences

For each of the following problems determine if the sequence is increasing, decreasing, not monotonic, bounded below, bounded above and/or bounded.

  1. \(\left\{ {\displaystyle \frac{1}{{4n}}} \right\}_{n = 1}^\infty \) Solution
  2. \(\left\{ {n{{\left( { - 1} \right)}^{n + 2}}} \right\}_{n = 0}^\infty \) Solution
  3. \(\left\{ {{3^{ - \,n}}} \right\}_{n = 0}^\infty \) Solution
  4. \(\left\{ {\displaystyle \frac{{2{n^2} - 1}}{n}} \right\}_{n = 2}^\infty \) Solution
  5. \(\left\{ {\displaystyle \frac{{4 - n}}{{2n + 3}}} \right\}_{n = 1}^\infty \) Solution
  6. \(\left\{ {\displaystyle \frac{{ - n}}{{{n^2} + 25}}} \right\}_{n = 2}^\infty \) Solution
