यदि गुणोत्तर श्रेढ़ी में \(a_3=20\) और (r=3) है, तो \(a_6\) क्या होगा?
If a geometric progression has \(a_3=20\) and (r=3), what will \(a_6\) be?
Explanation opens after your attempt
C. (540)
Concept
\(a_6=a_3r^3=20\cdot3^3=540\). To move forward from a given term, use the correct power of the ratio.
Why this answer is correct
The correct answer is C. (540). \(a_6=a_3r^3=20\cdot3^3=540\). To move forward from a given term, use the correct power of the ratio.
Exam Tip
\(a_6=a_3r^3=20\cdot3^3=540\)। दिए हुए पद से आगे जाने के लिए अनुपात की सही घात लगाएं।
