किसी अनुक्रम में \(R_1=1\) और (R_n=(n+2)R_{n-1}-1) है। \(R_4\) का मान क्या होगा?
In a sequence, \(R_1=1\) and (R_n=(n+2)R_{n-1}-1). What is the value of \(R_4\)?
Explanation opens after your attempt
D. तिरासी(83)
Concept
\(R_2=3\), \(R_3=14\), and \(R_4=83\). In exams, change the multiplier (n+2) at every step.
Why this answer is correct
The correct answer is D. तिरासी / (83). \(R_2=3\), \(R_3=14\), and \(R_4=83\). In exams, change the multiplier (n+2) at every step.
Exam Tip
\(R_2=3\), \(R_3=14\) और \(R_4=83\) मिलता है। परीक्षा में गुणक (n+2) को हर चरण पर बदलें।
