[tex] (\frac{1}{5} + \frac{1}{5n} )^{1} = ( \frac{1}{5} + \frac{1}{5})^{1} = \frac{2}{5} = 0.4 \\ ( \frac{1}{5} + \frac{1}{10})^{2} = ( \frac{2}{10} + \frac{1}{10} )^{2} = (\frac{3}{10} )^{2} = 0.09 \\( \frac{1}{5} + \frac{1}{15} )^{3} = ( \frac{3}{15} + \frac{1}{15} ) ^{3} = ( \frac{4}{15} )^{3} = \frac{64}{3375} = 0.01....[/tex]
