# Help me find my friend!

I need your help! My friend has gone missing and I have no clue where he could be! However, he did manage to get a message out to me:

Kidnapped. Send help. I am here:

port town. $$\left\lfloor\sqrt{\frac{x}{500334.5}}\right\rfloor$$, add $$^{\circ}\ '$$

- Rick

P.S. Remember my favourite three things!

Obviously, he hid the location, and that is where I need your help. To aid you, I vaguely remember him mentioning his favourite three things as fonts, the number 18 and the OEIS.

To send for help, I need both the city and country that he is currently in. Thanks for your help!

Hint:

Only the bold bits and the formula are relevant to the puzzle.

Extra notes (hints):

It turns out Rick was able to send another note:

Try writing the special part of the original message in a different font.

- Rick

And another:

When you find the two hidden numbers $$x$$ and $$y$$...
OEIS[x][y]

- Rick

• @mestackoverflow quite sure it is relevant. The degree and apostrophe look like they denote map coordinates. – yuzuki Jul 6 '16 at 8:13
• That's three pretty weird favorite things. – Dan Russell Jul 7 '16 at 19:41
• @DanRussell Not where we come from: PPCG – mbomb007 Jul 8 '16 at 21:34
• You can get some numbers from 'port town' if you change the font to Wingdings 2. – Wesley Situ Jul 8 '16 at 23:29
• @Jasen Sorry for the late reply, but here you go! imgur.com/V65VCSP – Wesley Situ Jul 28 '16 at 2:14

I think he is in:

port town:

It's italicized so that represents Italy, and it's a port town

I have no idea how that factors in

degree symbol:

':

again no idea

• Sorry, but this is incorrect. All of the pieces play a role in the solution. – GamrCorps Jul 6 '16 at 16:29
• @GamrCorps did i atleast get Italy correct? – Areeb Jul 6 '16 at 16:30
• Unfortunately, no. – GamrCorps Jul 6 '16 at 16:31
• Welp so much for that lead – Areeb Jul 6 '16 at 16:36

I'm not sure, but is your friend is in

France in Le Havre?

I vaguely remember him mentioning his favourite three things as fonts, the number 18 and the OEIS.

Searching for word OEIS, give me On-Line Encyclopedia of Integer Sequences

When I cross reference name of sequences with fonts, I found weird font and sequence.

I used 18th number from weird sequence (13510) in your formula, and that give me number 0.1643226573

and I draw lines on map with latitude and longtitude 0.1643226573.

Le Havre was biggest port town on my line, and hence my pick.

• Nope. Sorry. Not in France. – GamrCorps Jul 6 '16 at 17:13
