Question

calcular as razoes das progressões geométricas A- (3,12,48...) B-(-1,-3,-9,-27...)

Answer 1

$A=(3,12,48,...) \\ \\ a_1=3 \\ a_2=12 \\ a_3=48 \\ \\ raz\tilde{a}o \\ \frac{a_2}{a_1} = \frac{a_3}{a_2} \\ \\ \frac{12}{3} = \frac{48}{12} \\ \\ 4=4 \\ \\ r=q=4 \\ \\ B=(-1,-3,-9,-27,...) \\ \\ \frac{-3}{-1} = \frac{-9}{-3} \\ \\ 3=3 \\ \\ r=q=3$
