Find the next term: 5, 11, 23, 47, 95, ?
- 190
- 189
- 192
- 191
Explanation
📌 RULE / CONCEPT: If terms roughly double, test x2+1 or x2-1. 🧮 STEP-BY-STEP SOLUTION: Step 1: Each term = previous x 2 + 1: 5x2+1=11, 11x2+1=23 ... Step 2: 95x2+1 = 191. ✅ CORRECT ANSWER: (D) 191 ❌ WHY THE OTHER OPTIONS ARE WRONG: (A) 190 → ×2 only, forgot +1 (B) 189 → ×2 −1, wrong rule (5×2−1 = 9, not 11) (C) 192 → ×2 +2, wrong constantRelated MCQs
