f)(96, 32, ...)
g)(3, 12, 48, ...)
H0(3, -6, 12, -24, ...)
I)(100, 20, 4, ...)

Answer 1

Explicação passo-a-passo:

a)

$q = \frac{3}{3} = 1$

b)

$q = \frac{9}{3} = 3$

c)

$q = \frac{10}{20} = \frac{1}{2}$

d)

$q = \frac{20}{4} = 5$

e)

$q = \frac{5}{ - 1} = - 5$

f)

$q = \frac{32}{96} = \frac{2}{6}$

g)

$q = \frac{12}{3} = 4$

h)

$q = \frac{ - 6}{3} = - 2$

i)

$q = \frac{20}{100} = \frac{1}{5}$
