Question

DETERMINE A RAZÃO DE CADA UMA DAS SEGUINTES P.G
(3,12,48,...)
(10,5,...)
(5,-15,...)
(10,50,...)
(2,2⁵,...)
(√5,5,...)

Answer 1

(3,12,48,...)     q=4
(10,5,...)           q = 1/2
(5,-15,...)         q = -3
(10,50,...)        q = 5
(2,2⁵,...)           $q=2^4$
(√5,5,...)         q=√5

Answer 2

  (3,12,48,...) 
     q = 12/3 ==> q = 4

(10,5,...)
    q = 5/10 ==> q = 1/2

(5,-15,...)
   q = - 15/5 ==> q = - 3

(10,50,...)
    q = 50/10==> q = 5

(2,2⁵,...)
     q = 2^5/2==> q = 2^5.2^-1 ==> 2^4

(√5,5,...) 
     q = 5       ==>q=5^1.5^-1/2 ==> q= 5^1/2
           5^1/2
