Question

Hello guys

please help in solving this

Answer 1

Answer:

Step-by-step explanation:

product is 8,

So,

a/r *a * ar=8

a^3=8

a=2

Now sum is 7,

a/r +a + ar = 7

2/r + 2 + 2r = 7

2/r + 2r = 5

(2+2r^2)/r=5

2+2r^2= 5r

2r^2-5r+2=0

2r^2-4r-r+2=0

2r(r-2)-1(r-2)=0

(2r-1)(r-2)=0

r=1/2,2

Thus gp will be,

either 4,2,1

Or

1,2,4
