Question

Find the first five terms of each arithmetetic sequence describe a1 = -12 d = 5

Answer 1

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

$a_{1}$ = - 12

$a_{2}$ = - 12 + 5 = - 7

$a_{3}$ = - 7 + 5 = - 2

$a_{4}$ = - 2 + 5 = 3

$a_{5}$ = 3 + 5 = 8
