Question

dados os termos a1 determine os cinco primeiro termo de cada PG

a1=4 q=3


a1=20 q=2


a1=7 q=2

Answer 1

P.G.(4,12,36,108,324)
a 1 = 4
q = 3
a 2 = 4 x  3 = 12
a 3 = 12 x 3 = 36
a 4 = 36 x 3 = 108
a 5 = 108 x 3 = 324
----------------------------------------------------------------------
P.G.(20,40,80,160,320 )
q = 2
a 1 = 20
a 2 = 20 x 2 = 40
a 3 = 40 x 2 = 80
a 4 = 80 x 2 = 160
a 5 = 320
---------------------------------------------
P.G.(7,14,28,56,112 )
q = 2
a 1 = 7
a 2 = 7 x 2 = 14
a 3 = 14 x 2 = 28
a 4 = 28 x 2 = 56
a 5 = 56 x 2 = 112
