Explanation opens after your attempt
Correct Answer

B. \(\frac{1}{3}\)

Step 1

Concept

Here \(r=\frac{1}{3}\), so (a_8=729\cdot\left\(\frac{1}{3}\right\)7=\frac{1}{3}). In exams, apply fractional ratios carefully in decreasing GPs.

Step 2

Why this answer is correct

The correct answer is B. \(\frac{1}{3}\). Here \(r=\frac{1}{3}\), so (a_8=729\cdot\left\(\frac{1}{3}\right\)7=\frac{1}{3}). In exams, apply fractional ratios carefully in decreasing GPs.

Step 3

Exam Tip

यहाँ \(r=\frac{1}{3}\) है, इसलिए (a_8=729\cdot\left\(\frac{1}{3}\right\)7=\frac{1}{3}) है। परीक्षा में घटती GP में भिन्न अनुपात सावधानी से लगाएँ।
