यदि समांतर श्रेणी का (n)वाँ पद \(a_n=24-4n\) है, तो शून्य पद कौन-सा है?
If the (n)th term of an arithmetic progression is \(a_n=24-4n\), which term is zero?
Explanation opens after your attempt
C. (6)वाँ(6)th
Concept
From (24-4n=0), (n=6). For a zero term, set \(a_n\) equal to (0).
Why this answer is correct
The correct answer is C. (6)वाँ / (6)th. From (24-4n=0), (n=6). For a zero term, set \(a_n\) equal to (0).
Exam Tip
(24-4n=0) से (n=6)। शून्य पद के लिए \(a_n\) को (0) के बराबर रखें।
