Question

calcule a razão de cada P.G:
a) (3,15......)
b)(-6,-3......)
c)(8,8,8)

Answer 1

$\underbrace{\large{Progress\tilde{a}o \:\:\:geom\acute{e}trica}}$

• sequência numérica onde qualquer termo será obtido multiplicando o termo anterior por uma constante ( razão )

$\small{(a) (3,15......)}$

• $\small{q=\dfrac{a_2}{a_1}}$

• $\small{q=\dfrac{15}{3}}$

• $\underbrace{\small{q=5}}$

$\small{(b)(-6,-3......)}$

• $\small{q=\dfrac{a_2}{a_1}}$

• $\small{q=\dfrac{-3}{-6}}$

• $\underbrace{\small{q=2}}$

$\small{(c)(8,8,8)}$

• $\small{q=\dfrac{a_2}{a_1}}$

• $\small{q=\dfrac{8}{8}}$

• $\underbrace{\small{q=1}}$
