समांतर श्रेढ़ी \(1,6,11,16,\ldots\) का (25)वाँ पद ज्ञात कीजिए।
Find the (25)th term of the AP \(1,6,11,16,\ldots\).
Explanation opens after your attempt
Correct Answer
C. (121)
Concept
Here (a=1), (d=5), so \(a_{25}=1+24\times5=121\). The same formula works even for larger (n).
Why this answer is correct
The correct answer is C. (121). Here (a=1), (d=5), so \(a_{25}=1+24\times5=121\). The same formula works even for larger (n).
Exam Tip
यहाँ (a=1), (d=5) है, इसलिए \(a_{25}=1+24\times5=121\)। बड़े (n) में भी वही सूत्र लगता है।
