Explanation opens after your attempt
Correct Answer
A. \(\frac{40}{27}\)
Concept
The common ratio is \(\frac{1}{3}\), and (a_5=120\left\(\frac{1}{3}\right\)4=\frac{40}{27}). Use powers carefully with a fractional ratio.
Why this answer is correct
The correct answer is A. \(\frac{40}{27}\). The common ratio is \(\frac{1}{3}\), and (a_5=120\left\(\frac{1}{3}\right\)4=\frac{40}{27}). Use powers carefully with a fractional ratio.
Exam Tip
सार्व अनुपात \(\frac{1}{3}\) है और (a_5=120\left\(\frac{1}{3}\right\)4=\frac{40}{27})। भिन्न अनुपात में घात सावधानी से लगाएं।
