Answer 1

Answer:

3,6,12

Step-by-step explanation:

let first term a/r second is a and third is ar.

multiplication will be a/r×a×ar=216.

a^3=216

a=6.

a/r+a+ar= 21

put value of a=6.

6/r+6+6r=21

6/r+6r=21-6.

1/r+r=15/6.

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

compare both side

r=2,

So required GP will be 3,6,12.
