Concept:
In coding-decoding problems, each letter is shifted forward or backward in the alphabet according to a pattern.
Here, the pattern increases sequentially by \(+2, +3, +4, +5, +6, +7\).
Step 1: Observe the pattern from the given example.
\[
F \rightarrow H \quad (+2)
\]
\[
R \rightarrow U \quad (+3)
\]
\[
I \rightarrow M \quad (+4)
\]
\[
E \rightarrow J \quad (+5)
\]
\[
N \rightarrow T \quad (+6)
\]
\[
D \rightarrow K \quad (+7)
\]
Thus the pattern is \(+2, +3, +4, +5, +6, +7\).
Step 2: Apply the same pattern to ‘CANDLE'.
\[
C +2 = E
\]
\[
A +3 = D
\]
\[
N +4 = R
\]
\[
D +5 = I
\]
\[
L +6 = R
\]
\[
E +7 = J
\]
Step 3: Write the coded word.
\[
\text{CANDLE} \rightarrow \text{EDRIRJ}
\]
