यदि \(t_1=x\), \(t_n=2t_{n-1}+3\) और \(t_4=61\) है, तो (x) का मान क्या होगा?

If \(t_1=x\), \(t_n=2t_{n-1}+3\), and \(t_4=61\), what is the value of (x)?

Correct Answer

A. पाँच(5)

Step 1

Concept

\(t_4=8x+21\), so (x=5). In exams, expand the rule up to \(t_1\) and solve.

Step 2

Why this answer is correct

The correct answer is A. पाँच / (5). \(t_4=8x+21\), so (x=5). In exams, expand the rule up to \(t_1\) and solve.

Step 3

Exam Tip

\(t_4=8x+21\), इसलिए (x=5) है। परीक्षा में नियम को \(t_1\) तक फैलाकर हल करें।
