Final Answer:
The code for 'PROPER' in the given language is QTSQJFS.
Step-by-step explanation:
In the given code language, each letter of the word 'shadow' is shifted by a specific number of positions. Let's analyze the pattern:
S -> R (shifted back by 1)
H -> J (shifted forward by 2)
A -> B (shifted forward by 1)
D -> F (shifted forward by 2)
O -> N (shifted back by 2)
W -> Y (shifted forward by 2)
Applying the same pattern to 'PROPER':
P -> Q (shifted forward by 1)
R -> T (shifted forward by 1)
O -> O (no shift)
P -> Q (shifted forward by 1)
E -> J (shifted forward by 5)
R -> F (shifted back by 2)
Therefore, 'PROPER' is coded as QTSQJFS in the given language.
