- 44
- 36
- 42
- 40
Explanation
📌 RULE / CONCEPT: Take differences first; if they rise by a fixed step, add the next step. 🧮 STEP-BY-STEP SOLUTION: Step 1: Pattern n(n+1): 1x2, 2x3, 3x4, 4x5, 5x6, so next is 6x7 = 42. Step 2: Differences 4,6,8,10,12 confirm it. ✅ CORRECT ANSWER: (C) 42 ❌ WHY THE OTHER OPTIONS ARE WRONG: (A) 44 → adds 14, skips the next gap 12 (B) 36 → adds only 6, no pattern (D) 40 → adds 10 again, ignores that the gap grows by 2Related MCQs
