Explanation opens after your attempt
Correct Answer
A. \( \frac{25}{4}\)
Concept
The common ratio is \(\frac{1}{2}\), and (a_5=100\left\(\frac{1}{2}\right\)4=\frac{25}{4}). Use powers carefully with a fractional ratio.
Why this answer is correct
The correct answer is A. \( \frac{25}{4}\). The common ratio is \(\frac{1}{2}\), and (a_5=100\left\(\frac{1}{2}\right\)4=\frac{25}{4}). Use powers carefully with a fractional ratio.
Exam Tip
सार्व अनुपात \(\frac{1}{2}\) है और (a_5=100\left\(\frac{1}{2}\right\)4=\frac{25}{4})। भिन्न अनुपात में घात सावधानी से लगाएं।
