यदि \(a_n=5\cdot4^{n-1}\) है, तो \(\frac{a_7}{a_4}\) का मान क्या है?
If \(a_n=5\cdot4^{n-1}\), what is the value of \(\frac{a_7}{a_4}\)?
Explanation opens after your attempt
Correct Answer
C. (64)
Concept
\(\frac{a_7}{a_4}=r^3=4^3=64\). In the same progression, the ratio of terms depends on the difference of positions.
Why this answer is correct
The correct answer is C. (64). \(\frac{a_7}{a_4}=r^3=4^3=64\). In the same progression, the ratio of terms depends on the difference of positions.
Exam Tip
\(\frac{a_7}{a_4}=r^3=4^3=64\)। समान श्रेढ़ी में पदों का अनुपात पद-संख्या के अंतर पर निर्भर करता है।
