यदि किसी समान्तर श्रेणी का (11)वां पद (52) और (d=5) है, तो \(a_2\) क्या होगा?
If the (11)th term of an AP is (52) and (d=5), what is \(a_2\)?
Explanation opens after your attempt
A. (7)
Concept
\(a_2=a_{11}-9d=52-45=7\). When moving backward from a known term, subtract the position gap times (d).
Why this answer is correct
The correct answer is A. (7). \(a_2=a_{11}-9d=52-45=7\). When moving backward from a known term, subtract the position gap times (d).
Exam Tip
\(a_2=a_{11}-9d=52-45=7\)। ज्ञात पद से पीछे आने पर स्थानों का अंतर गुणा करके घटाएं।
