Understanding the Coding Pattern
This question asks us to decipher a coding pattern based on an example and apply it to a new word. The example shows 'CAT' being coded as 'FDW'. This suggests a consistent rule is applied to each letter.
Analyzing the 'CAT' to 'FDW' Code
Let's examine the letter shifts using their positions in the English alphabet (A=1, B=2, C=3, ...):
- C is the 3rd letter. It is coded as F, which is the 6th letter. The shift is \(6 - 3 = 3\).
- A is the 1st letter. It is coded as D, which is the 4th letter. The shift is \(4 - 1 = 3\).
- T is the 20th letter. It is coded as W, which is the 23rd letter. The shift is \(23 - 20 = 3\).
The pattern identified is that each letter is replaced by the letter 3 positions after it in the alphabet (a Caesar cipher with a shift of +3).
| Original Letter | Coded Letter | Position Shift |
|---|---|---|
| C | F | \(+3\) |
| A | D | \(+3\) |
| T | W | \(+3\) |
Applying the +3 Shift to 'DOG'
To find the code for 'DOG', we apply the same \(+3\) shift rule to each letter:
- D: The letter 'D' is the 4th letter of the alphabet. Adding the shift: \(4 + 3 = 7\). The 7th letter is G.
- O: The letter 'O' is the 15th letter of the alphabet. Adding the shift: \(15 + 3 = 18\). The 18th letter is R.
- G: The letter 'G' is the 7th letter of the alphabet. Adding the shift: \(7 + 3 = 10\). The 10th letter is J.
Combining these results, 'DOG' is coded as 'GRJ'.
