Explanation opens after your attempt
Correct Answer
B. \({}^{n}C_{\frac{n-1}{2}}\) और \({}^{n}C_{\frac{n+1}{2}}\)\({}^{n}C_{\frac{n-1}{2}}\) and \({}^{n}C_{\frac{n+1}{2}}\)
Concept
For odd (n), the two middle indices are complementary and equal. In exams remember two largest terms for the odd case.
Why this answer is correct
The correct answer is B. \({}^{n}C_{\frac{n-1}{2}}\) और \({}^{n}C_{\frac{n+1}{2}}\) / \({}^{n}C_{\frac{n-1}{2}}\) and \({}^{n}C_{\frac{n+1}{2}}\). For odd (n), the two middle indices are complementary and equal. In exams remember two largest terms for the odd case.
Exam Tip
Odd (n) में two middle indices complementary और equal होते हैं। परीक्षा में odd case में दो largest terms याद रखें।
