अनुक्रम \(\frac{6}{5},\frac{9}{8},\frac{14}{13},\frac{21}{20},\ldots\) का सामान्य पद कौन-सा है?
What is the general term of the sequence \(\frac{6}{5},\frac{9}{8},\frac{14}{13},\frac{21}{20},\ldots\)?
Explanation opens after your attempt
A. \(a_n=\frac{n^2+5}{n^2+4}\)
Concept
The numerator is \(n^2+5\) and the denominator is \(n^2+4\), so \(a_n=\frac{n^2+5}{n^2+4}\). Identify square patterns in fractional sequences.
Why this answer is correct
The correct answer is A. \(a_n=\frac{n^2+5}{n^2+4}\). The numerator is \(n^2+5\) and the denominator is \(n^2+4\), so \(a_n=\frac{n^2+5}{n^2+4}\). Identify square patterns in fractional sequences.
Exam Tip
अंश \(n^2+5\) और हर \(n^2+4\) है इसलिए \(a_n=\frac{n^2+5}{n^2+4}\)। भिन्न अनुक्रम में वर्ग पैटर्न पहचानें।
