Question

insira 4 meios geométricos entre -2 e 2

Answer 1

P.G.(-2,,A 2 ,A 3 ,A 4 , A 5 .2)
A 1 = - 1 
A 6 = 2
A 6 = A 1 . q^n - 1
2 = - 2 . q^6-1
2/-2 = q^5
-1 = q^5
q ^5 = - 1
q = ⁵√-1
q = -1
a 1 = -2
a 2 = -2 . -1 = 2
a 3 = 2.-1 = -2
a 4 = -2.-1 = 2
a 5 = 2.-1 = -2
a 6 = -2.-1 = 2
P.G.(-2,2,-2,2,-2,2)
