Question

considere uma progressa geimétrica de termo inicial 1/40 e razão 2. Qual o sexto termo progressão

Answer 1

$> \: resolucao \\ \\ \geqslant \: progressao \: geometrica \\ \\ a1 = \frac{1}{40} \\ q = 2 \\ \\ = = = = = = = = = = \\ \\ > \: o \: sexto \: termo \: da \: pg$

$an = a1 \times q {}^{n - 1} \\ an = \frac{1}{40} \times 2 {}^{6 - 1} \\ an = \frac{1}{40} \times 2 {}^{5} \\ an = \frac{1}{40} \times 32 \\ an = \frac{32 \div 8}{40 \div 8} \\ an = \frac{4}{5} \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \geqslant$
