Question

1. Find the next four terms in the following arithmetic sequence: -3, -6, -9, -12,

Answer 1

Explanation:

d=-6+3=-9+6=-12+9=-3

a(n) = a +(n-1)d

a(n) = -3+(n-1)-3

The next three terms:

a(5) = -3+(5-1)-3=-15

a(6) = -3+(6-1)-3=-18

a(7) = -3+(7-1)-3=-21

a(8) = -3+(8-1)-3=-24

hope this helps
