यदि \(a_2=24\), \(r=\frac{1}{2}\) है, तो \(a_5\) क्या होगा?
If \(a_2=24\) and \(r=\frac{1}{2}\), what will be \(a_5\)?
Explanation opens after your attempt
Correct Answer
B. (3)
Concept
(a_5=a_2r-3=24\left\(\frac{1}{2}\right\)3=3). Moving three positions forward uses \(r^3\).
Why this answer is correct
The correct answer is B. (3). (a_5=a_2r-3=24\left\(\frac{1}{2}\right\)3=3). Moving three positions forward uses \(r^3\).
Exam Tip
(a_5=a_2r-3=24\left\(\frac{1}{2}\right\)3=3)। तीन पद आगे जाने पर \(r^3\) लगता है।
