यदि \(a_n=4\cdot3^{n-1}\) है, तो \(a_4+a_6\) का मान क्या होगा?
If \(a_n=4\cdot3^{n-1}\), what will be the value of \(a_4+a_6\)?
Explanation opens after your attempt
B. (1080)
Concept
\(a_4=108\) and \(a_6=972\), so the sum is (1080). Find both terms separately and add them.
Why this answer is correct
The correct answer is B. (1080). \(a_4=108\) and \(a_6=972\), so the sum is (1080). Find both terms separately and add them.
