C. 364
दिया गया नियम है: अगला पद = \(3\times\) पिछला पद \(+1\)। अतः \(121\) के बाद का पद \(3\times121+1=363+1=364\) होगा। \(363\) केवल \(121\) का तीन गुना है; उसमें \(1\) जोड़ना भी आवश्यक है। परीक्षा टिप: अनुक्रम में दिया हुआ नियम अंतिम पद पर सीधे लागू करके उत्तर जाँचें। / The rule is: next term = \(3\times\) previous term \(+1\). Therefore, the term after \(121\) is \(3\times121+1=363+1=364\). Option 363 is only three times 121 and misses the added 1. Exam tip: apply the stated rule directly to the last given term.
