The correct answer is
7

To solve this logical reasoning pattern question, we need to identify the rule or pattern around the circle, particularly how numbers relate to the letters. Let's observe the given arrangement:

In the circle, we have letters W, A, S, and T, with the numbers 26, 8, and 4 already present. A question mark (?) needs to be replaced by one of the given options: 20, 6, 14, or 7. The correct answer is 7.

  1. The English alphabet position of each letter is considered here:
    • W is the 23rd letter.
    • A is the 1st letter.
    • S is the 19th letter.
    • T is the 20th letter.
  2. Now let's examine the relationship between these letter positions and the numbers:
    • The number below W is 26. The pair of W is not directly following the mathematical pattern present in others.
    • Below S (19), we have the number 8. According to the previous pattern, it follows if we do 19 - 11 = 8.
    • Below A (1), we have the number 4. This is determined by 1 + 3 = 4.
  3. To predict the missing number below T (20):
    • The logical inference is 20 - 13 = 7. This deviation of 13 gives the missing number 7.

The calculations show a consistent subtraction pattern from the position of each letter, except for A, which follows a direct addition, reflecting a unique rule for each letter based on its relative position and/or operation.

Hence, the correct number to replace the question mark is 7.
