Show answer & explanation
Correct answer: D
1. Analyze the differences between consecutive terms: 45-37=8, 49-45=4, 65-49=16, 79-65=14. 2. Observe that if the term 49 is replaced by 53, the differences become: 45-37=8, 53-45=8, 65-53=12, 79-65=14. 3. The pattern of differences becomes consistent (8, 8, 12, 14), making 49 the incorrect term. Final Answer: Option B
