Question

Dados o termo A₁, e a razão Q, determine os cincos primeiros termos de cada P.G.
a) a₁ = -80; q = -1/4

b) a₁ = √3; q = 1/ √3

c) a₁ = 0,5; q = -0,2

Answer 1

a)

$\mathsf{(-80,20,-5,\dfrac{5}{4},-\dfrac{5}{16})}$

b)

$\mathsf{(\sqrt{3},1,\dfrac{1}{\sqrt{3}},\dfrac{1}{3},\dfrac{1}{3\sqrt{3}})}$

c)

$\mathsf{(0,5~,-\dfrac{5}{2},\dfrac{1}{2},-\dfrac{1}{10},\dfrac{1}{50})}$
