Analyzing the Letter-to-Number Mapping

The problem provides initial values: A = 2 and D = 5. We observe that the standard alphabetical position for A is 1 and for D is 4. The given values suggest a pattern where the numerical value assigned to each letter is its alphabetical position plus 1.

Let's verify this pattern using the given value for SEA = 28:

• S is the 19^th letter; Value = 19 + 1 = 20
• E is the 5^th letter; Value = 5 + 1 = 6
• A is the 1^st letter; Value = 1 + 1 = 2
• SEA = 20 + 6 + 2 = 28. The pattern holds true.

Calculating the Value for COUNTRY

We apply the established pattern (Letter Value = Alphabetical Position + 1) to the letters in the word COUNTRY:

• C: 3^rd letter -> 3 + 1 = 4
• O: 15^th letter -> 15 + 1 = 16
• U: 21^st letter -> 21 + 1 = 22
• N: 14^th letter -> 14 + 1 = 15
• T: 20^th letter -> 20 + 1 = 21
• R: 18^th letter -> 18 + 1 = 19
• Y: 25^th letter -> 25 + 1 = 26

Determining the Final Sum

Now, sum the calculated values for each letter in COUNTRY:

COUNTRY = 4 + 16 + 22 + 15 + 21 + 19 + 26

COUNTRY = 123

The calculated value for COUNTRY is 123, which matches the first option.
