यदि किसी समान्तर श्रेणी का (S_n=5n(2n-1)) है तो (12)वाँ पद क्या होगा?

If (S_n=5n(2n-1)) for an arithmetic progression, what is the (12)th term?

Explanation opens after your attempt
Correct Answer

C. (225)

Step 1

Concept

\(a_{12}=S_{12}-S_{11}=1380-1155=225\). Exam tip: subtract consecutive sums for a particular term.

Step 2

Why this answer is correct

The correct answer is C. (225). \(a_{12}=S_{12}-S_{11}=1380-1155=225\). Exam tip: subtract consecutive sums for a particular term.

Step 3

Exam Tip

\(a_{12}=S_{12}-S_{11}=1380-1155=225\) है। परीक्षा में किसी खास पद के लिए लगातार योग घटाएं।
