Question

Dada a P.G(1, 2, 4, 8,...), calcule o décimo termo dessa progressão geométrica: An= a₁. qn-1​

Answer 1

$> \: resolucao \\ \\ \geqslant \: progressao \: \: geometrica \\ \\ q = \frac{a2}{a1} = \frac{2}{1} = 2 \\ \\ = = = = = = = = = = = =$

$> \: o \: 10 \: termo \: da \: pg \\ \\ an = a1 \times q {}^{n - 1} \\ an = 1 \times 2 {}^{10 - 1} \\ an = 1 \times 2 {}^{9} \\ an = 1 \times 512 \\ an = 512 \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \geqslant \geqslant$
