Answer 1

$> resolucao \\ \\ \geqslant progressao \: geometrica \\ \\ q = \frac{a2}{a1} \\ \\ q = \frac{ \frac{5}{2} }{10} \\ \\ q = \frac{5}{2} \times \frac{1}{10} \\ \\ q = \frac{5}{20} \\ \\ q = \frac{1}{4} \\ \\ \\ an = a1 \times q {}^{n - 1} \\ an = 10 \times ( \frac{1}{4} ) {}^{6 - 1} \\ an = 10 \times ( \frac{1}{4} ) {}^{5} \\ an = 10 \times \frac{1}{1024} \\ an = \frac{10}{1024} \\ an = \frac{5}{512} \\ \\ \\ > < > < > < > < > < >$
