यदि (a=11) और \(a_6=352\) है तथा (r) धनात्मक है, तो (r) क्या होगा?
If (a=11) and \(a_6=352\), and (r) is positive, what is (r)?
Explanation opens after your attempt
A. (2)
Concept
From \(352=11r^5\), \(r^5=32=2^5\), so (r=2). In exams, use \(r^5\) for the sixth term.
Why this answer is correct
The correct answer is A. (2). From \(352=11r^5\), \(r^5=32=2^5\), so (r=2). In exams, use \(r^5\) for the sixth term.
Exam Tip
\(352=11r^5\) से \(r^5=32=2^5\), इसलिए (r=2) है। परीक्षा में छठे पद के लिए \(r^5\) लगाएँ।
