Answer:
6 IS THE ANSWER....
Step-by-step explanation:
Let numbers are a-d, a ,a+d
A.T.Q. ,...
a-d+a+a+d=18
3a=18
a=6
again A.T.Q ,....
6-d+2,6+4,6+d+11 are in G.P.
so,..
8-d,10 and 17+d are in G.P.
10/8-d=17+d/10
(17+d)(8-d)=100
136+8d-17d-d^2=100
d^2+9d-36=0
d^2+12d-3d-36=0
d(d+12)-3(d+12)=0
d=3,-12
if d=3
numbers are 6-3,6,6+3
I.e.3,6,9
if d=-12
numbers are 18,6,-6
Hope it helps you dear....
