गुणोत्तर श्रेढ़ी \(6,12,24,\ldots\) का (7)वाँ पद क्या है?
What is the (7)th term of the geometric progression \(6,12,24,\ldots\)?
Explanation opens after your attempt
C. (384)
Concept
Here (r=2), so \(a_7=6\cdot2^6=384\). Use \(a_n=ar^{n-1}\) in a geometric progression.
Why this answer is correct
The correct answer is C. (384). Here (r=2), so \(a_7=6\cdot2^6=384\). Use \(a_n=ar^{n-1}\) in a geometric progression.
Exam Tip
यहाँ (r=2), इसलिए \(a_7=6\cdot2^6=384\)। गुणोत्तर श्रेढ़ी में \(a_n=ar^{n-1}\) लगाएं।
