I really can't see the solution to it, maybe a fresh pair of eyes will see it.
Well the easy stupid answer is to see this as 2 sets of 3 numbers the first set 3,8,18 that looks like the difference doubles 3+5=8 then 8+10=18
If you do the same for the second set of 3
30 +40 =70
so the next must be 70+80 (=2*40) =150
But this is so ridiculous arbitrary yet simple but who decided the rules are to break in 2 sets of 3 each.
