यदि \(b_n=3b_{n-1}+2\) और \(b_3=44\) है, तो \(b_1\) का मान क्या होगा?
If \(b_n=3b_{n-1}+2\) and \(b_3=44\), what is the value of \(b_1\)?
Explanation opens after your attempt
A. चार(4)
Concept
\(b_3=9b_1+8\), so \(b_1=4\). In exams, expand the recursive rule up to the first term.
Why this answer is correct
The correct answer is A. चार / (4). \(b_3=9b_1+8\), so \(b_1=4\). In exams, expand the recursive rule up to the first term.
Exam Tip
\(b_3=9b_1+8\), इसलिए \(b_1=4\) है। परीक्षा में पुनरावर्ती नियम को पहले पद तक फैलाएँ।
