Question

2-Determine a razão das seguintes P.A.: A) (0,4,8,12,16) B) (5,3,1,-1,3) C) (-3,0,3,6,…) D) (-2,-1,0,1,2,3

Answer 1

Explicação passo-a-passo:

A) (0,4,8,12,16)

r=a2-a1

r=4-0

r=4

B) (5,3,1,-1,3)

r=a2-a1

r=3-5

r=-2

C) (-3,0,3,6,…)

r=a2-a1

r=0+3

r= 3

D) (-2,-1,0,1,2,3)

r=a2-a1

r=-1+2

r= 1
