यदि किसी गुणोत्तर श्रेढ़ी में (a=6) और (r=2) है, तो पहले चार पद कौन-से होंगे?
If a geometric progression has (a=6) and (r=2), what are the first four terms?
Explanation opens after your attempt
B. (6,12,24,48)
Concept
The first term is (6), and multiplying by (2) each time gives (6,12,24,48). In a geometric progression each next term is formed by multiplication.
Why this answer is correct
The correct answer is B. (6,12,24,48). The first term is (6), and multiplying by (2) each time gives (6,12,24,48). In a geometric progression each next term is formed by multiplication.
Exam Tip
पहला पद (6) है और हर बार (2) से गुणा करने पर (6,12,24,48) मिलते हैं। गुणोत्तर श्रेढ़ी में अगला पद गुणा करके बनता है।
