अनुक्रम \(\frac{2}{3},\frac{5}{4},\frac{10}{5},\frac{17}{6},\ldots\) का सामान्य पद कौन-सा है?
What is the general term of the sequence \(\frac{2}{3},\frac{5}{4},\frac{10}{5},\frac{17}{6},\ldots\)?
Explanation opens after your attempt
A. \(a_n=\frac{n^2+1}{n+2}\)
Concept
The numerator is \(n^2+1\) and the denominator is (n+2), so \(a_n=\frac{n^2+1}{n+2}\). In a fractional sequence identify the numerator pattern separately.
Why this answer is correct
The correct answer is A. \(a_n=\frac{n^2+1}{n+2}\). The numerator is \(n^2+1\) and the denominator is (n+2), so \(a_n=\frac{n^2+1}{n+2}\). In a fractional sequence identify the numerator pattern separately.
Exam Tip
अंश \(n^2+1\) और हर (n+2) है इसलिए \(a_n=\frac{n^2+1}{n+2}\)। भिन्न अनुक्रम में अंश का अलग पैटर्न पहचानें।
