let the first 2 terms of the gp be a & ar
a+ar=9                                 t4=2*t3
a(1+r)=9                             ar^3=2*ar^2
substituting r value             ar^3/ar^2=2
 a(1+2)=9                               r=2
3a=9
a=3
 t2=2*3=6
 t3=4*3=12
t4=8*3=24
 the terms in a gp are 3,6,12,24....
