hey mate!
HERE IS YOUR ANSWER
STEP BY STEP EXPLANATION:
According to the question,
4th term =18
i.e a+3d=18......(1)
and 15th term - 9th term=30
i.e a+14d-(a+8d)=30....(2)
a+14d-a-8d=30
14d-8d=30
6d=30
d=30/6
d=5
now, putting the value of d in equation (1) i.e a+3d=18
so, a+3(5)=18
a+15=18
a=18-15
a=3
A.P is 3,8,13,18...
HOPE IT HELPED ^_^
