यदि \(a_n=9n+2\) है, तो समानांतर श्रेढ़ी का पहला पद क्या है?
If \(a_n=9n+2\), what is the first term of the arithmetic progression?
Explanation opens after your attempt
B. (11)
Concept
For the first term (n=1), so \(a_1=9+2=11\). To find the first term from \(a_n\), put (n=1).
Why this answer is correct
The correct answer is B. (11). For the first term (n=1), so \(a_1=9+2=11\). To find the first term from \(a_n\), put (n=1).
Exam Tip
पहले पद के लिए (n=1), इसलिए \(a_1=9+2=11\)। \(a_n\) में पहला पद निकालने के लिए (n=1) रखें।
