a) (2,6,18,...)
b) (243,81,27,...)
c) (π, π, π, π, ...)
d) (-4,8,-16,...)
e) (72,48,32,...)
f) (4,2v2,2,...)

Answer 1

Resposta:Segue as respostas abaixo na explicação

Explicação passo a passo:

a) (2,6,18,...)-->q=a2/q1--->q=6/2--->q=3

b) (243,81,27,...)--->q=81/243:81/81-->q=1/3

c) (π, π, π, π, ...)--->q=a2/a1--->q=π/π--->q=1

d) (-4,8,-16,...)--->q=a2/a1--->q=8/-4--->q=-2

e) (72,48,32,...)--->q=48/72:24/24-->q=2/3

f) (4,2v2,2,...)--->q=2√2/4:2/2--->1√2/2
