Letter Number Pattern Reasoning

This question involves identifying a logical pattern between a letter and a number, and applying it to find the missing number.

Pattern Identification

• Find the alphabetical position for each letter. 'C' is the 3rd letter and 'E' is the 5th letter.
• Observe the relationship between the position number and the given number for 'C'.
• Position of 'C' = 3. Given number = 27. The relationship is $3^3 = 27$.

Applying the Pattern

• The established pattern is: (Alphabetical Position)$^3$.
• Apply this pattern to the letter 'E'.
• Alphabetical Position of 'E' = 5.
• Calculate the number using the pattern: $5^3$.
• $5^3 = 5 \times 5 \times 5 = 125$.

Therefore, the number that replaces the question mark is 125.
