    $\begingroup$ Downvotes are likely a combination of two things: 1, Puzzles that aren't yours should only be posted with proper attribution. This is important to fix, because we hold a very dim view of plagiarism and it can result in question deletion and sometimes bannings. 2, puzzles of this style, while on-topic, are sometimes downvoted as not being particularly interesting, or due to only being soluble in multiple-choice format. $\endgroup$ – Sconibulus Jun 22 '17 at 16:58

    $\begingroup$ -1 for a diagram so poor, its characters are less legible than plain text. But not -1 for posting a maths puzzle. Maths puzzles are on topic and are OK. $\endgroup$ – Rosie F Jun 22 '17 at 18:53

Answer is equal to:

30

Reason:

2 + 1 = 3,
3 + 2 = 5,
5 + 3 = 8,
8 + 4 = 12,
12 + 5 = 17,
17 + 6 = 23,
23 + 7 = 30,
30 + 8 = 38.
We're adding an incremented counter to the values and the path is left to right, down, right to left, down, left to right.

ANSWER IS

30
first series 2+1 = 3, 3+2 = 5 increasing
second series 17-5 = 12, 12-4 = 8 decreasing
third series 23+7 = 30, 30+8 = 38 increasing
