Explanation opens after your attempt
Correct Answer
C. 35
Simple Explanation
क्रमागत पदों के अंतर क्रमशः \(3,4,5,6\) हैं। इसलिए पाँचवें पद \(20\) के बाद छठा पद \(20+7=27\) और सातवाँ पद \(27+8=35\) होगा। अतः सही उत्तर \(35\) है। \(27\) केवल छठा पद है। परीक्षा टिप: ऐसे क्रमों में पहले पदों के अंतर लिखकर अगला अंतर पहचानें। / The differences between consecutive terms are \(3,4,5,6\). Therefore, after the fifth term \(20\), the sixth term is \(20+7=27\), and the seventh term is \(27+8=35\). Hence, the correct answer is \(35\). Note that \(27\) is only the sixth term. Exam tip: write the successive differences to identify the next increment in such sequences.
