यदि \(e_1=3\) और \(e_n=2e_{n-1}+n\) है, तो \(e_5-e_4\) का मान क्या होगा?
If \(e_1=3\) and \(e_n=2e_{n-1}+n\), what is the value of \(e_5-e_4\)?
Explanation opens after your attempt
A. सैंतालीस(47)
Concept
\(e_4=42\) and \(e_5=89\), so the difference is (47). In exams, find both terms separately first.
Why this answer is correct
The correct answer is A. सैंतालीस / (47). \(e_4=42\) and \(e_5=89\), so the difference is (47). In exams, find both terms separately first.
Exam Tip
\(e_4=42\) और \(e_5=89\), इसलिए अंतर (47) है। परीक्षा में पहले दोनों पद अलग-अलग निकालें।
