Qual é o quinto termo da pg( 4860,1620...) ? URGENTE!!!

Answer 1

$> \: resolucao \\ \\ \geqslant \: progressao \: geometrica \\ \\ q = \frac{a2}{a1} = \frac{1620}{4860} = \frac{1}{3} \\ \\ = = = = = = = = = = = \\ \\ > \: o \: quinto \: termo \: da \: pg \\ \\ an = a1 \times q {}^{n - 1} \\ an = 4860 \times ( \frac{1}{3} ) {}^{5 - 1} \\ an = 4860 \times ( \frac{1}{3} ) {}^{4} \\ an = 4860 \times \frac{1}{81} \\ an = \frac{4860}{81} \\ an = 60 \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant$

Answer 2

Vamos lá.

PG

u1 = 4860

u2 = 1620

q = u2/u1 = 1/3

u3 = 1620/3 = 540

u4 = 540/3 = 180

u5 = 180/3 = 60
