Question

ESCREVA A P.G DE CINCO TERMOS
A)A1=3 E Q=2 B)A1=32 E Q= A UM SOBRE QUATROO

Answer 1

P.G(3,6,12,24,48 )
q = 2
a 2 = a 1 . q^n - 1
a 2 = 3 . 2^2-1
a 2 = 3 . 2
a 2 = 6
a 3 = 6 .2
a 3 = 12
a 4 = 12 . 2 
a 4 = 24
a 5 = 24 . 2
a 5 = 48
P.G(32,8 , 2,1/2,1/8)
q = 1/4
a 2 = a 1 . (1/4)^n - 1
a 2 = 32 . (1/4)^2-1
a 2 = 32 . 1/4
a 2 = 32/4
a 2 = 8
a 3 = 8.1/4
a 3 = 2
a 4 = 2 . 1/4
a 4 = 1/2
a 5 = 1/2 . 1/4
a 5 = 1/8
