Answer:

- 12, - 7, - 2, 3, 8

Step-by-step explanation:

The general terms of an arithmetic sequence are

a, a + d, a + 2d + ....... + a + (n - 1 )d

To obtain consecutive terms in the sequence add d = 5 to the previous term

[tex]a_{1}[/tex] = - 12

[tex]a_{2}[/tex] = - 12 + 5 = - 7

[tex]a_{3}[/tex] = - 7 + 5 = - 2

[tex]a_{4}[/tex] = - 2 + 5 = 3

[tex]a_{5}[/tex] = 3 + 5 = 8
