Show answer & explanation
Correct answer: B. 216
Explanation
Pattern: each term = 2 × previous + a number that increases by 1: 4×2+2 = 10, 10×2+3 = 23, 23×2+4 = 50, 50×2+5 = 105. So next = 105×2 + 6 = 216.नियम: प्रत्येक पद = पिछला पद × 2 + एक संख्या जो 1 से बढ़ती है: 4×2+2 = 10, 10×2+3 = 23, 23×2+4 = 50, 50×2+5 = 105। अतः अगला पद = 105×2 + 6 = 216।More Reasoning & Mental Ability questions
