Question

Obter a razão de cada PG: a)(2√2, 4√6,24√2) b- (-12,-3,0,75) c- (1,2,4,8,16,...) d- (-2,6,-18,54,...) e- (5,-5,5,-5,5,...) f - (80,40,20,10,5,...)

Answer 1

Resposta:

Explicação passo-a-passo:

a) (2√2, 4√6,24√2)

q = 4√6 / 2√2 = 2√3

b) (-12, -3, -0,75)

q = -3 / -12 = 0,25

c- (1,2,4,8,16,...)

q = 2 / 1 = 2

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

q = 6/-2 = -3

e- (5,-5,5,-5,5,...)

q = -5/5 = -1

f - (80,40,20,10,5,...)

q = 40/80 = 0,5
