Correct Answer: 257 / 257
First differences are 10, 24, 44, 70; their differences are 14, 20, 26, rising by 6, so the next first-difference is 70 + 32 = 102 and 155 + 102 = 257. / प्रथम अंतर 10, 24, 44, 70 हैं; इनके अंतर 14, 20, 26 हैं जो 6 से बढ़ रहे हैं, अतः अगला प्रथम अंतर 70 + 32 = 102 होगा और 155 + 102 = 257।
