यदि गुणोत्तर श्रेणी \(x,,3x,,9x,\ldots\) में छठा पद (2430) है, तो (x) क्या है?

If the sixth term of the geometric progression \(x,,3x,,9x,\ldots\) is (2430), what is (x)?

Explanation opens after your attempt
Correct Answer

B. (10)

Step 1

Concept

The sixth term is \(x\cdot3^5=243x=2430\), so (x=10). In exams, put the algebraic first term in \(ar^{n-1}\) too.

Step 2

Why this answer is correct

The correct answer is B. (10). The sixth term is \(x\cdot3^5=243x=2430\), so (x=10). In exams, put the algebraic first term in \(ar^{n-1}\) too.

Step 3

Exam Tip

छठा पद \(x\cdot3^5=243x=2430\) है, इसलिए (x=10) है। परीक्षा में बीजीय पहले पद को भी \(ar^{n-1}\) में रखें।
