Question

Find three terms in AP such that their sum is 3 and product is -8

Answer 1

let the three terms be (a-d), a and (a+d),

then according to the question, se have

a-d + a + a+d=3,

3a=3,

a=1,


also

(a-d)×a×(a+d)=-8,

(1-d)×1×(1+d)=-8,

(1-d²)=-8,

then

1+9=d²,

9=d²,

then

d=√9,

d=+-3
