Answer 2

2,3,4

Step-by-step explanation:

Let the three numbers are (a-r) ,a and (a+r).

(a-r) , a and (a+r) are in A.P. ........[Given]

Thus,

(a-r) + a + (a+r)=a+a+a

9=3a.

a=3..............(1)

Now

(a-r)a(a+r)=24

(3-r)3(3+r)=24 ....................[From (1) ]

9-r^2=8

r^2=1

r=1

Thus, the three numbers are,

(a-r)=3-1=2

a=3

(a+r)=3+1=4

Thus, the answer is 2,3,4.
