गुणोत्तर श्रेणी \(625,125,25,5,\ldots\) का छठा पद क्या है?
What is the sixth term of the geometric progression \(625,125,25,5,\ldots\)?
Explanation opens after your attempt
B. \(\frac{1}{5}\)
Concept
Here \(r=\frac{1}{5}\), so the sixth term is (625\cdot\left\(\frac{1}{5}\right\)5=\frac{1}{5}). In exams, apply fractional ratios carefully in decreasing GPs.
Why this answer is correct
The correct answer is B. \(\frac{1}{5}\). Here \(r=\frac{1}{5}\), so the sixth term is (625\cdot\left\(\frac{1}{5}\right\)5=\frac{1}{5}). In exams, apply fractional ratios carefully in decreasing GPs.
Exam Tip
यहाँ \(r=\frac{1}{5}\) है, इसलिए छठा पद (625\cdot\left\(\frac{1}{5}\right\)5=\frac{1}{5}) है। परीक्षा में घटती GP में भिन्न अनुपात सावधानी से लगाएँ।
