Question

calcule as razões das progressões aritméticas
a)(0,5,10,15...)
b)(4,6,8,10...)
c)(-4,-6,-8,-10...)
d)(16,12,8,4...)
e)(-4,1,6...)
f)(0,7,14...)
g)(-10,-7,-4...)​

Answer 1

Resposta:

a) r = 5

b) r = 2

c) r = - 2

d) r = - 4

e) r = 5

f) r = 7

g) r = 3

Explicação passo-a-passo:

a) (0,5,10,15...)

r = 5 - 0 = 5

b) (4,6,8,10...)

r = 6 - 4 = 2

c) (-4,-6,-8,-10...)

r = - 6 - (- 4) = - 6 + 4 = - 2

d) (16,12,8,4...)

r = 12 - 16 = - 4

e) (-4,1,6...)

1 - (- 4) = 1 + 4 = 5

f) (0,7,14...)

r = 7 - 0 = 7

g) (-10,-7,-4...)

r = - 7 - (- 10) = - 7 + 10 = 3​
