Decoding the COPPER to FQTRJT Pattern

The problem asks us to find the coded word for SILVER based on the pattern used to encode COPPER as FQTRJT. We need to identify the relationship between the letters of the original word and the coded word.

Identifying the Letter Shift Pattern

Let's map the letters of COPPER to FQTRJT and determine the shift in their alphabetical positions:

• C (position 3) → F (position 6) : Shift = $6 - 3 = +3$
• O (position 15) → Q (position 17) : Shift = $17 - 15 = +2$
• P (position 16) → T (position 20) : Shift = $20 - 16 = +4$
• P (position 16) → R (position 18) : Shift = $18 - 16 = +2$
• E (position 5) → J (position 10) : Shift = $10 - 5 = +5$
• R (position 18) → T (position 20) : Shift = $20 - 18 = +2$

The pattern of shifts applied to COPPER is: +3, +2, +4, +2, +5, +2.

Applying the Pattern to SILVER

Now, we apply the same sequence of shifts (+3, +2, +4, +2, +5, +2) to the letters of the word SILVER:

• S (position 19) + 3 shifts → 19 + 3 = 22 → V
• I (position 9) + 2 shifts → 9 + 2 = 11 → K
• L (position 12) + 4 shifts → 12 + 4 = 16 → P
• V (position 22) + 2 shifts → 22 + 2 = 24 → X
• E (position 5) + 5 shifts → 5 + 5 = 10 → J
• R (position 18) + 2 shifts → 18 + 2 = 20 → T

Resulting Coded Word

Combining the shifted letters, the word SILVER is coded as VKPXJT.
