कौन-सा कथन \(12,6,3,\frac{3}{2},\ldots\) के लिए सही है?
Which statement is correct for \(12,6,3,\frac{3}{2},\ldots\)?
Explanation opens after your attempt
Correct Answer
B. यह \(r=\frac{1}{2}\) वाली गुणोत्तर श्रेढ़ी हैIt is a geometric progression with \(r=\frac{1}{2}\)
Concept
Each term is half of the previous term, so \(r=\frac{1}{2}\). To check the ratio divide the next term by the previous term.
Why this answer is correct
The correct answer is B. यह \(r=\frac{1}{2}\) वाली गुणोत्तर श्रेढ़ी है / It is a geometric progression with \(r=\frac{1}{2}\). Each term is half of the previous term, so \(r=\frac{1}{2}\). To check the ratio divide the next term by the previous term.
Exam Tip
हर पद पिछले पद का आधा है, इसलिए \(r=\frac{1}{2}\) है। अनुपात जांचने के लिए अगला पद पिछले पद से भाग दें।
