let first term be X
let second term be X +1
let 3rd term be X +2
now.. X + X +1 + X +2 =30
3x+3=30
3x= 30-3
X= 27/3
X = 9
now 1st term is 9
2nd term is 9+1=10
and 3rd term is 9+2 =11
hope it helps....

Answer:
30 = 3/2 (a + 2d)
a + 2d = 60/3
a + 2d = 20 --> eq 1
a1 *a2*a3= 360-->
a1= a
a2= a+d
a3= a+2d
a * (a+d) * (a+2d) = 360
a^2 + 3ad + 2d^2 = 360/a
