यदि \(a_n=7\cdot3^{n-1}\) है, तो \(\frac{a_5}{a_3}\) का मान क्या है?
If \(a_n=7\cdot3^{n-1}\), what is the value of \(\frac{a_5}{a_3}\)?
Explanation opens after your attempt
C. (9)
Concept
\(\frac{a_5}{a_3}=r^2=3^2=9\). In the same progression, the ratio of terms depends on the difference of positions.
Why this answer is correct
The correct answer is C. (9). \(\frac{a_5}{a_3}=r^2=3^2=9\). In the same progression, the ratio of terms depends on the difference of positions.
Exam Tip
\(\frac{a_5}{a_3}=r^2=3^2=9\)। समान श्रेढ़ी में पदों का अनुपात पद-संख्या के अंतर पर निर्भर करता है।
