कौन-सा कथन \(18,6,2,\frac{2}{3},\ldots\) के लिए सही है?
Which statement is correct for \(18,6,2,\frac{2}{3},\ldots\)?
Explanation opens after your attempt
Correct Answer
B. यह \(r=\frac{1}{3}\) वाली गुणोत्तर श्रेढ़ी हैIt is a geometric progression with \(r=\frac{1}{3}\)
Concept
Each term is \(\frac{1}{3}\) of the previous term, so \(r=\frac{1}{3}\). To check the ratio divide the next term by the previous term.
Why this answer is correct
The correct answer is B. यह \(r=\frac{1}{3}\) वाली गुणोत्तर श्रेढ़ी है / It is a geometric progression with \(r=\frac{1}{3}\). Each term is \(\frac{1}{3}\) of the previous term, so \(r=\frac{1}{3}\). To check the ratio divide the next term by the previous term.
Exam Tip
हर पद पिछले पद का \(\frac{1}{3}\) है, इसलिए \(r=\frac{1}{3}\) है। अनुपात जांचने के लिए अगला पद पिछले पद से भाग दें।
