f) ( -1, -5, -25,-125, -625)

Answer 1

Resposta:

Explicação passo-a-passo:

a) (3,9,27,81)

q = 9/3 = 3

b) (2, -6, 18, -54.....)

q = -6/2 = - 3

c) (20, 10, 5, 2,5 ....)

q = 10/20 = 0,5

d)( 3,3,3,3....)

q = 3/3 = 1

e) ( -4, -20, -100....)

q = -20/-4 = 5

f) ( -1, -5, -25,-125, -625)

q = -5/-1 = 5
