18. 1+3=4, 3+4=7, 4+7=11, 7+11=18

18 because 4-1=3 7-3=4 11-4=7 so 18-7=11

1+3 = 4
3+4 = 7
4+7 = 11
7+11= 18

1+3 = 4
3+4 = 7
4+7 = 11
7+11 =18
Next in the series is 18

It would be 18, b/c the next term is the sum of the previous two terms:
4 = 1+3
7 = 3+4
11 = 4+7
18 = 7+11

18 seems like the most likely, because the simplest explaination is that the sequence uses the sum of previous two terms, so 1 +3 = 4, 3+4 = 7, and 7+11 = 18.
That's because it's considered better to take the simplest solution, over one that is not as simple. There are certainly sequences that start with 1,3,4, 7,11 and continue with any of the numbers above, or for that matter, any other number. What you're being tested on, is your ability to see the simplest pattern.
But don't just accept it's the ONLY possible solution, it's not.
