\({}^{n}C_r+{}^{n}C_{r+1}\) को Pascal identity से किस रूप में लिखा जाएगा?
Using Pascal identity, \({}^{n}C_r+{}^{n}C_{r+1}\) is written in which form?
Explanation opens after your attempt
Correct Answer
A. \({}^{n+1}C_{r+1}\)
Concept
Adjacent lower indices (r) and (r+1) give the (r+1) term of the next row. In exams identify Pascal pattern quickly.
Why this answer is correct
The correct answer is A. \({}^{n+1}C_{r+1}\). Adjacent lower indices (r) and (r+1) give the (r+1) term of the next row. In exams identify Pascal pattern quickly.
Exam Tip
Adjacent lower indices (r) और (r+1) मिलकर next row का (r+1) term देते हैं। परीक्षा में Pascal pattern तुरंत पहचानें।
