If \(a_n=6n-17\), which is the first positive term?
Explanation opens after your attempt
B. (3)वाँ(3)rd
Concept
\(a_2=-5\) and \(a_3=1\), so the first positive term is the (3)rd. Check \(a_n>0\) for positive terms.
Why this answer is correct
The correct answer is B. (3)वाँ / (3)rd. \(a_2=-5\) and \(a_3=1\), so the first positive term is the (3)rd. Check \(a_n>0\) for positive terms.
Exam Tip
\(a_2=-5\) और \(a_3=1\), इसलिए पहला धनात्मक पद (3)वाँ है। धनात्मक पद के लिए \(a_n>0\) जांचें।
