Which value of (x) makes (4,20,x) a geometric progression?
Explanation opens after your attempt
C. (100)
Concept
The common ratio is \(\frac{20}{4}=5\), so \(x=20\cdot5=100\). Multiply the second term by the ratio to get the third term.
Why this answer is correct
The correct answer is C. (100). The common ratio is \(\frac{20}{4}=5\), so \(x=20\cdot5=100\). Multiply the second term by the ratio to get the third term.
Exam Tip
सार्व अनुपात \(\frac{20}{4}=5\) है, इसलिए \(x=20\cdot5=100\)। तीसरे पद के लिए दूसरे पद को अनुपात से गुणा करें।
