Cevap

The coded word for PROJECT is RHQGPWV.
The code follows a dual positional rule: letters at odd positions (1st, 3rd, 5th, 7th) are shifted forward by 2 positions in alphabetical order, while letters at even positions (2nd, 4th, 6th) are replaced by their reverse alphabetical counterpart (A↔Z, B↔Y, etc.) followed by a 1-letter backward shift. Applying these exact steps to PROJECT gives RHQGPWV.

Adım Adım Çözüm

1
Analyze the rule applied to letters at odd positions (1st, 3rd, 5th, 7th) in GLIMMER.
G (1st) → I (+2 steps forward), I (3rd) → K (+2 steps forward), M (5th) → O (+2 steps forward), R (7th) → T (+2 steps forward).
Establishes that letters at odd positions undergo a direct +2 forward alphabetical shift.
2
Analyze the rule applied to letters at even positions (2nd, 4th, 6th) in GLIMMER.
L (2nd, reverse letter O) → N (-1 step backward), M (4th, reverse letter N) → M (-1 step backward), E (6th, reverse letter V) → U (-1 step backward).
Establishes that letters at even positions are replaced by their opposite alphabetical letter (where A=Z, B=Y, etc.) and then shifted 1 letter backward.
3
Apply the odd-position transformation (+2 forward shift) to the target word PROJECT.
P (1st) → R, O (3rd) → Q, E (5th) → G, T (7th) → V.
Determines the output letters for positions 1, 3, 5, and 7.
4
Apply the even-position transformation (reverse letter - 1 step) to the target word PROJECT.
R (2nd, reverse I) → H, J (4th, reverse Q) → P, C (6th, reverse X) → W.
Determines the output letters for positions 2, 4, and 6.
5
Combine all transformed positions sequentially.
Position 1 to 7 yields RHQGPWV.
Finalizes the code for PROJECT.
