Answer:

Step-by-step explanation:

Let a-d,a,a+d three numbers in AP

(a-d)+(a)+(a+d) = -3

3a = -3;

a = -3/3 = -1

Given that their product is 8

(a-d)(a)(a+d) = 8

(a^{2} -d^{2})(-1) = 8

(a^{2} -d^{2}) = 8/-1 = -8

(1 - d^{2}) = -8

d^{2} = -8-1; d^{2} = -9

d = ±3

a = -1,d = 3     and a = -1,d = -3

a-d,a,a+d        and     a-d,a,a+d

-4,-1,2              and       2,-1,-4
