    $\begingroup$ Hollup, this is not a duplicate, the numbers are different. $\endgroup$ Commented Jun 29, 2017 at 4:58

    $\begingroup$ It doesn't look to me like it's the same. With the other one, once you see what's going on the answer is obvious. With this one, at least for me, applying the idea from the other one doesn't make anything obvious. $\endgroup$

    $\begingroup$ Is there actually a clear defined answer? For sequence puzzles like these it is possible to make a case for practically any number being correct. How do we know which one is the intended solution? $\endgroup$ Commented Jun 29, 2017 at 18:43

    $\begingroup$ The "I have to answer urgently" line lets me assume that the OP does not know the answer, which makes this puzzle rather... bad. Also, the tagging lets one assume it is really just about finding the answer to "18,114,158,X,338" which makes it really bad and very differnt form the "original" which had some out-of-the-box-but-obvious solution. I'm therefore voting to close unless the post is somewhat improved. $\endgroup$

The car is parked in spot

274. The difference between 18 and 158 is 140, 158 and 338 is 180. Therefore 114 + 160 = 274

    $\begingroup$ How do you infer "160" of just two numbers (140 and 180) ? What makes you assume that "+20" is the way to go? It could as well be $* Sqrt(9/7)$.. $\endgroup$

    $\begingroup$ (Not saying that your solution isn't "beautiful", but if it is the correct solution, the puzzle is really bad in my eyes.) $\endgroup$

  • $\begingroup$ If it's the solution it's also not a very good sequence, as the first two numbers aren't really related, but it got stuck in my head because it was so oddly "neat" $\endgroup$

That number might be 294.

It starts with number 18.

18 x 6 + 6 = 114

18 x 8 + 14 = 158

18 x 16 + 6 = 294

18 x 18 + 14 = 338

I here use some sequences. Also the last digit 4 8 4 8 4 also recursive with my answer.
