यदि \(a_{18}=5a_6-8\) और \(a_6=31\) है, तो \(a_{30}\) क्या होगा?

If \(a_{18}=5a_6-8\) and \(a_6=31\), what is \(a_{30}\)?

Explanation opens after your attempt
Correct Answer

A. (263)

Step 1

Concept

\(a_{18}=147\) and (12d=116), so \(d=\frac{29}{3}\). \(a_{30}=147+12\cdot\frac{29}{3}=263\).

Step 2

Why this answer is correct

The correct answer is A. (263). \(a_{18}=147\) and (12d=116), so \(d=\frac{29}{3}\). \(a_{30}=147+12\cdot\frac{29}{3}=263\).

Step 3

Exam Tip

\(a_{18}=147\) और (12d=116), इसलिए \(d=\frac{29}{3}\)। \(a_{30}=147+12\cdot\frac{29}{3}=263\)।
