# Enigma between Colleagues (Part2)

Let's give a second try with something more creative.

Here is the sequence :

161 = B

198 = W

173 = ∅

246 = B

215 = W

227 = B

192 = ∅

184 = ?

Don't hesitate to comment some improvement for our next enigma :)

Hint 1:

Welcome on board of this not so colorful enigma.

I think the answer is

184 = B

Reasoning

First convert each number to hexadecimal.
Notice that some of these hexadecimal numbers correspond to squares on a chessboard in algebraic notation.
If such a square is black, the number maps to B, if it is white, it maps to W and if it is not a chessboard square, it maps to ∅.

Explicitly,
161 $$\rightarrow$$ a1 $$\rightarrow$$ black square $$\rightarrow$$ B
198 $$\rightarrow$$ c6 $$\rightarrow$$ white square $$\rightarrow$$ W
173 $$\rightarrow$$ ad $$\rightarrow$$ not a square $$\rightarrow$$
246 $$\rightarrow$$ f6 $$\rightarrow$$ black square $$\rightarrow$$ B
215 $$\rightarrow$$ d7 $$\rightarrow$$ white square $$\rightarrow$$ W
227 $$\rightarrow$$ e3 $$\rightarrow$$ black square $$\rightarrow$$ B
192 $$\rightarrow$$ c0 $$\rightarrow$$ not a square $$\rightarrow$$
184 $$\rightarrow$$ b8 $$\rightarrow$$ black square $$\rightarrow$$ B
