Answer

The word 'GARDEN' is coded as 'ICTFGP'.
The underlying coding rule shifts each letter forward by 2 positions in alphabetical order (+2+2). Applying this +2+2 shift to 'GARDEN' produces GIG \rightarrow I, ACA \rightarrow C, RTR \rightarrow T, DFD \rightarrow F, EGE \rightarrow G, and NPN \rightarrow P, which forms the word 'ICTFGP'.

Step-by-Step Solution

1
Determine the rule governing the given coded word pair.
Comparing 'FLOWER' to 'HNQYGT': F+2=HF+2=H, L+2=NL+2=N, O+2=QO+2=Q, W+2=YW+2=Y, E+2=GE+2=G, and R+2=TR+2=T. The pattern is a uniform forward shift of +2+2 positions in the alphabet.
Identifying the step size and direction of letter shifts.
2
Apply the +2+2 forward shift rule to each letter of the word 'GARDEN'.
G+2=IG+2=I, A+2=CA+2=C, R+2=TR+2=T, D+2=FD+2=F, E+2=GE+2=G, N+2=PN+2=P.
Transforming the letters of the target word using the established rule.
