I make it SL.

First letter sequence is: +1 -2 +3 -4 (N +5 = S)
Second letter sequence is: +1 -2 +1 -2 (K +1 = L)

Treat as two seperate sequences, first letters and second letters, find the relationship and apply next step.

P +1 Q -2 O +3 R -4 N so +5 gives S

( interstingly enough if you do every second one you get Q,R,....S)

Repeat for M N L M K
+1 -2 +1 -2 so K +1 gives L

answer SL


Beaten by a faster typer. :lol:
