ME AJUDEM POR FAVOR
COM CÁLCULO

Answer 1

Boa tarde!

A) (5,15,45...)

a2=15

a1=5

q=a2/a1 → 15/5 = 3

________________

B) (-13,-3,-0,75...)

a2=-3

a1=-13

q=a2/a1 → -3/-13 ≅ 0,23 → 23/100

________________

C) (7,21,63,...)

a2=21

a1=7

q=a2/a1 → 21/7 = 3

________________

D) (-8,-90,-9000,...)

a2=-90

a1=-8

q=-90/-8 = 11,25 → 1125/100 → 225/20 → 45/4
