Question

1) Calcula a razão das progressões geométricas b) (81, 27, 9, ...)​

Answer 1

$> resolucao \\ \\ \geqslant progressao \: geometrica \\ \\ q = \frac{a2}{a1} \\ q = \frac{27}{81} \\ q = \frac{1}{3} \\ \\ = = = = = = = = = = = = = = = = \\ \\ q = \frac{a3}{a2} \\ q = \frac{9}{27} \\ q = \frac{1}{3} \\ \\ > < > < > < > < > < > < > >$
