Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: 5
Concept: Interleaved Alternating Series.

Formula: Split into two sub-series based on odd/even positions.

Solution:

  • Odd terms: 1, 2, 3, 4, 5


  • Even terms: 4, 5, 6, 7


  • The 9th position corresponds to the odd sub-series: \(4 + 1 = 5\).


Why other options are incorrect:

• Options B, C, and D: Fail to decouple the two underlying alternating sequences.
