If the sum of the first \(n\) natural numbers is \(S_n=25,425\), what is the value of \(n\)?यदि पहले \(n\) प्राकृतिक संख्याओं का योग \(S_n=25,425\) है, तो \(n\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 225225
Use \(S_n=\frac{n(n+1)}{2}\). So \(\frac{n(n+1)}{2}=25,425\Rightarrow n(n+1)=50,850\). Check \(n=225\): \(225\cdot 226=50,850\), so it works. Therefore \(n=225\).\(S_n=\frac{n(n+1)}{2}\) का उपयोग करें। इसलिए \(\frac{n(n+1)}{2}=25,425\Rightarrow n(n+1)=50,850\)। \(n=225\) जाँचें: \(225\cdot 226=50,850\), इसलिए यह सही है। अतः \(n=225\)।
