अनुक्रम \(\frac{5}{2},\frac{8}{5},\frac{13}{10},\frac{20}{17},\ldots\) का सामान्य पद कौन-सा है?
What is the general term of the sequence \(\frac{5}{2},\frac{8}{5},\frac{13}{10},\frac{20}{17},\ldots\)?
Explanation opens after your attempt
A. \(a_n=\frac{n^2+4}{n^2+1}\)
Concept
The numerator is \(n^2+4\) and the denominator is \(n^2+1\), so \(a_n=\frac{n^2+4}{n^2+1}\). In a fractional sequence identify square patterns separately.
Why this answer is correct
The correct answer is A. \(a_n=\frac{n^2+4}{n^2+1}\). The numerator is \(n^2+4\) and the denominator is \(n^2+1\), so \(a_n=\frac{n^2+4}{n^2+1}\). In a fractional sequence identify square patterns separately.
Exam Tip
अंश \(n^2+4\) और हर \(n^2+1\) है इसलिए \(a_n=\frac{n^2+4}{n^2+1}\)। भिन्न अनुक्रम में अंश और हर के वर्ग पैटर्न अलग पहचानें।
