a)(1,3,9,27...)
b) (3,6,12,24...)
c) (-2,4,-8...)
d) (1,4,16...)
e) (5,-15,45...)​

Answer 1

Resposta:

a) q = 3

b) q = 2

c) q = -2

d) q = 4

e) q = -3

Explicação passo-a-passo:

a) (1,3,9,27...)

q = 3/1 = 3

b) (3,6,12,24...)

q = 6/3 = 2

c) (-2,4,-8...)

q = 4/-2 = -2

d) (1,4,16...)

q = 4/1 = 4

e) (5,-15,45...)​

q = -15/5 = -3
