यदि \(a_n=22-4n\) है तो पहला ऋणात्मक पद कौन-सा होगा?
If \(a_n=22-4n\), which will be the first negative term?
Explanation opens after your attempt
Correct Answer
B. (6)वाँ/(6)th
Step 1
Concept
\(a_5=2\) and \(a_6=-2\), so the first negative term is the (6)th. Do not count zero or positive terms as negative.
Step 2
Why this answer is correct
The correct answer is B. (6)वाँ / (6)th. \(a_5=2\) and \(a_6=-2\), so the first negative term is the (6)th. Do not count zero or positive terms as negative.
Step 3
Exam Tip
\(a_5=2\) और \(a_6=-2\) है, इसलिए पहला ऋणात्मक पद (6)वाँ है। शून्य या धनात्मक पद को ऋणात्मक न मानें।
