यदि \(a_n=48\left(\frac{1}{2}\right)^{n-1}\) है, तो \(a_3+a_5\) का मान क्या है?
If \(a_n=48\left(\frac{1}{2}\right)^{n-1}\), what is the value of \(a_3+a_5\)?
Explanation opens after your attempt
B. (15)
Concept
\(a_3=12\) and \(a_5=3\), so the sum is (15). Use powers carefully with a fractional ratio.
Why this answer is correct
The correct answer is B. (15). \(a_3=12\) and \(a_5=3\), so the sum is (15). Use powers carefully with a fractional ratio.
Exam Tip
\(a_3=12\) और \(a_5=3\), इसलिए योग (15) है। भिन्न अनुपात में घात सावधानी से लगाएं।
