Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: LAK
Concept: Constant and Variable Letter Shifts.

Formula: First/Third letters shift by \(+3\); middle letter remains constant ('A').

Solution:

  • 1st letter: C \(\xrightarrow{+3}\) F \(\xrightarrow{+3}\) I \(\xrightarrow{+3}\) L


  • 2nd letter: A \(\to\) A \(\to\) A \(\to\) A


  • 3rd letter: B \(\xrightarrow{+3}\) E \(\xrightarrow{+3}\) H \(\xrightarrow{+3}\) K


Term = LAK.

Why other options are incorrect:

Option A: Shifts first letter by \(+1\) instead of \(+3\).
