Answer:

Let a be the first term and r be the common ratio of the G.P

a  

1

​  

=a, a  

2

​  

=ar, a  

3

​  

=ar  

2

, a  

4

​  

=ar  

3

 

By the given condition,

a  

3

​  

=a  

1

​  

+9

⇒ar  

2

=a+9....(1)

a  

2

​  

=a  

4

​  

+18

⇒ar=ar  

3

+18....(2)

From (1) and (2), we get

a(r  

2

−1)=9....(3)

ar(1−r  

2

)=18....(4)

Dividing (4) and (3), we get

a(r  

2

−1)

ar(1−r  

2

)

​  

=  

9

18

​  

 

⇒−r=2

⇒r=−2

Substituting the value of r in (1), we get

4a=a+9

⇒3a=9

∴a=3

⇒a  

1

​  

=3

⇒a  

2

​  

=3(−2)=−6

⇒a  

3

​  

=3(−2)  

2

=12

⇒a  

4

​  

=3(−2)  

3

=−24

Thus the first four numbers of the G.P are 3,-6,12 and -24.
