तर्क: पंक्तियों में, तीसरी संख्या, पहले दो अंकों के वर्ग का योगफल है और फिर उन अंकों का कुल योग करें।

पहली पंक्ति में,

⇒ (9)2 + (8)2 + (9 + 8) = 81 + 64 + 17 = 162

दूसरी पंक्ति में,

⇒ (11)2 + (6)2 + (11 + 6) = 121 + 36 + 17 = 174

इसी प्रकार, तीसरी पंक्ति में,

⇒ (8)2 + (13)2 + (8 + 13) = 64 + 169 + 21 = 254

अतः लुप्त पद "254" है।
