Answer 2

$\frac{1}{5 \times 6} + \frac{1}{6 \times 7} + \frac{1}{7 \times 8} + \frac{1}{8 \times 9} + \frac{1}{9 \times 10} + \frac{1}{10 \times 11} + \frac{1}{11 \times 12} + \frac{1}{12 \times 13} + \frac{1}{13 \times 14} \\ = (\frac{1}{5} - \frac{1}{6} ) + (\frac{1}{6} - \frac{1}{7} ) + (\frac{1}{7} - \frac{1}{8} ) + (\frac{1}{8} - \frac{1}{9} ) + (\frac{1}{9} - \frac{1}{10} ) +(\frac{1}{10} - \frac{1}{11} ) + (\frac{1}{11} - \frac{1}{12} ) + (\frac{1}{12} - \frac{1}{13} ) + (\frac{1}{13} - \frac{1}{14} ) \\ = \frac{1}{5} - \frac{1}{6} + \frac{1}{6} - \frac{1}{7} + \frac{1}{7} - \frac{1}{8} + \frac{1}{8} - \frac{1}{9} + \frac{1}{9} - \frac{1}{10} + \frac{1}{11} - \frac{1}{12} + \frac{1}{12} - \frac{1}{13} + \frac{1}{13} - \frac{1}{14} \\ = \frac{1}{5} - \frac{1}{14} \\ = \frac{14 - 5}{70} \\ = \frac{9}{70}$
