Question

Determine a razão de cada PA. a) (5, 10, 15, 20, 25, 30) b) (12, 9, 6, 3, 0, -3) c) (2, 2, 2, 2, 2,...)

Answer 1

✔OLÁ!!!

A) (5, 10, 15, 20, 25, 30)

A2 - A1

10 - 5 = 5

Razão = 5

B) (12, 9, 6, 3, 0, -3)

A2 - A1

9 - 12 = - 3

Razão = - 3

C) (2, 2, 2, 2, 2,...)

A2 - A1

2 - 2 = 0

Razão = 0
