यदि \(a_6=1024\) और (r=2) है, तो पहला पद (a) क्या होगा?
If \(a_6=1024\) and (r=2), what is the first term (a)?
Explanation opens after your attempt
C. (32)
Concept
\(a_6=ar^5\), so \(1024=a\cdot32\) and (a=32). In exams, divide the sixth term by \(r^5\).
Why this answer is correct
The correct answer is C. (32). \(a_6=ar^5\), so \(1024=a\cdot32\) and (a=32). In exams, divide the sixth term by \(r^5\).
Exam Tip
\(a_6=ar^5\), इसलिए \(1024=a\cdot32\) और (a=32) है। परीक्षा में छठे पद से \(r^5\) भाग दें।
