well
x = 3 + d
y = 3 + 2 d
18 = 3 + 3 d
--------------------------
d = (18 -3)/3 = 15/3 = 5
I suspect you can find x and y now :)
x = 3 + d
y = 3 + 2 d
18 = 3 + 3 d

d = (18 -3)/3 = 15/3 = 5

x-3 = y-x = 18-y
a=3
x=3+d
y = 3+2d
18=3+3d ---> 6 = 1+d
d = 5
then we have 3,8,13,18
or there are 3 differences from 3 to 18
or (18-3)/3 = 5
then form your sequence
a=3
x=3+d
y = 3+2d
