Why this answer is correct
The correct answer is B. \(a_n=95-7n\). At (n=1) it gives (88) and at (n=2) it gives (81) so \(a_n=95-7n\). In exams check the first two terms of a decreasing sequence.
Exam Tip
(n=1) पर (88) और (n=2) पर (81) मिलता है इसलिए \(a_n=95-7n\) है। परीक्षा में घटते अनुक्रम के पहले दो पद जाँचें।
