यदि \(f_1=4\) और \(f_n=2f_{n-1}+3\) है, तो \(f_n>150\) पहली बार किस (n) पर होगा?
If \(f_1=4\) and \(f_n=2f_{n-1}+3\), for which (n) will \(f_n>150\) first occur?
Explanation opens after your attempt
C. छह(6)
Concept
\(f_5=109\) and \(f_6=221\), so the condition is first satisfied at (n=6). In exams, choose the first term that crosses the limit.
Why this answer is correct
The correct answer is C. छह / (6). \(f_5=109\) and \(f_6=221\), so the condition is first satisfied at (n=6). In exams, choose the first term that crosses the limit.
Exam Tip
\(f_5=109\) और \(f_6=221\), इसलिए पहली बार (n=6) पर शर्त पूरी होती है। परीक्षा में सीमा पार करने वाला पहला पद चुनें।
