Question

CALCULE A RAZÃO DE CADA UMA, SEGUINTES PROGRESSÕES GEOMÉTRICAS.
a) (1,2,4,8,16...)
b) (-2,6,-18,54...)
c) (80,40,20,10,5...)
d) (4,12,36,108...)

Answer 1

a
( 1, 2,4,8,16 )
q = 2/1 = 2 ***
b
( -2, 6,-18, 54 )
q = 6/-2 = -3 ***
c
( 80, 40, 20, 10, 5)
q = 40/80 = 4/8 = 1/2 ***
d
( 4; 12;36, 108 )
q = 12/4 = 3 ***
