यदि \(a_5=24\) और \(a_9=2a_5+28\) है तो \(a_{25}\) क्या होगा?

If \(a_5=24\) and \(a_9=2a_5+28\), what is \(a_{25}\)?

Explanation opens after your attempt
Correct Answer

B. (280)

Step 1

Concept

\(a_9=76\) and (4d=52), so (d=13). \(a_{25}=24+20\times13=284\).

Step 2

Why this answer is correct

The correct answer is B. (280). \(a_9=76\) and (4d=52), so (d=13). \(a_{25}=24+20\times13=284\).

Step 3

Exam Tip

\(a_9=76\) और (4d=52) इसलिए (d=13)। \(a_{25}=24+20\times13=284\)।
