Which sequence is not a geometric progression?
Explanation opens after your attempt
Correct Answer
C. \(2,4,8,15,\ldots\)
Concept
In \(2,4,8,15,\ldots\), the ratios \(2,2,\frac{15}{8}\) are not equal. A geometric progression must have a constant ratio.
Why this answer is correct
The correct answer is C. \(2,4,8,15,\ldots\). In \(2,4,8,15,\ldots\), the ratios \(2,2,\frac{15}{8}\) are not equal. A geometric progression must have a constant ratio.
Exam Tip
\(2,4,8,15,\ldots\) में अनुपात \(2,2,\frac{15}{8}\) बराबर नहीं हैं। गुणोत्तर श्रेढ़ी में अनुपात स्थिर होना चाहिए।
