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 views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.

Section 4-1 : Sequences

For problems 1 & 2 list the first 5 terms of the sequence.

1. $$\left\{ \frac{{4n}}{{{n^2} - 7}}} \right\}_{n = 0}^\infty$$ Solution
2. $$\left\{ \frac{{{{\left( { - 1} \right)}^{n + 1}}}}{{2n + {{\left( { - 3} \right)}^n}}}} \right\}_{n = 2}^\infty$$ Solution

For problems 3 – 6 determine if the given sequence converges or diverges. If it converges what is its limit?

1. $$\left\{ \frac{{{n^2} - 7n + 3}}{{1 + 10n - 4{n^2}}}} \right\}_{n = 3}^\infty$$ Solution
2. $$\left\{ \frac{{{{\left( { - 1} \right)}^{n - 2}}{n^2}}}{{4 + {n^3}}}} \right\}_{n = 0}^\infty$$ Solution
3. $$\left\{ \frac{{{{\bf{e}}^{5n}}}}{{3 - {{\bf{e}}^{2n}}}}} \right\}_{n = 1}^\infty$$ Solution
4. $$\left\{ \frac{{\ln \left( {n + 2} \right)}}{{\ln \left( {1 + 4n} \right)}}} \right\}_{n = 1}^\infty$$ Solution
