The correct answer is
TQO

To solve this Logical Reasoning question, we need to identify the pattern in each of the given letter-clusters and determine which one is the odd one out. Let's analyze the options:

  1. Consider the letter-cluster TQO:
    • The positions of the letters in the alphabet are T = 20, Q = 17, O = 15.
    • Observe the pattern: From 20 to 17, we subtract 3; from 17 to 15, we subtract 2.
    • This pattern follows a decreasing difference in sequence (subtracting 3, then 2).
  2. Consider the letter-cluster IGE:
    • The positions of the letters in the alphabet are I = 9, G = 7, E = 5.
    • Observe the pattern: From 9 to 7, we subtract 2; from 7 to 5, we subtract 2.
    • This pattern follows a consistent difference (subtracting 2 each time).
  3. Consider the letter-cluster MKI:
    • The positions of the letters in the alphabet are M = 13, K = 11, I = 9.
    • Observe the pattern: From 13 to 11, we subtract 2; from 11 to 9, we subtract 2.
    • This pattern also follows a consistent difference of 2.
  4. Consider the letter-cluster ECA:
    • The positions of the letters in the alphabet are E = 5, C = 3, A = 1.
    • Observe the pattern: From 5 to 3, we subtract 2; from 3 to 1, we subtract 2.
    • This pattern too follows a consistent difference of 2.

After analyzing all options, we see that IGE, MKI, and ECA follow a consistent pattern of subtracting 2 between each letter. However, the letter-cluster TQO is different as it follows a decreasing pattern subtracting 3, then 2. Hence, TQO is the odd one out.

Conclusion: The letter-cluster that is different is TQO.
