Good. This is another way to look at it.
In more general terms : Given a number x, next number in the series is: 2x+2.

Yes! The answer is 38. The difference doubles every time.

3 + 5 = 8
8 + 10 = 18
18 + 20 = 38
38 + 40 = 78

In the series the difference of first n second is 5
And second and third is 10 I.e.,

8-3=5
18-8=10=5*2
So, next number is third no+(thirdno - secondno)*2
So, 18+10*2=38

And similarly next no sets as 38+20*2=78

This can't really be an actual interview question ... an elementary schooler could figure this out.
