यदि (6,x,150) धनात्मक गुणोत्तर श्रेढ़ी के लगातार पद हैं, तो (x) का मान क्या है?
If (6,x,150) are consecutive terms of a positive geometric progression, what is the value of (x)?
Explanation opens after your attempt
B. (30)
Concept
\(x^2=6\cdot150=900\), so positive (x=30). The middle term is the geometric mean.
Why this answer is correct
The correct answer is B. (30). \(x^2=6\cdot150=900\), so positive (x=30). The middle term is the geometric mean.
Exam Tip
\(x^2=6\cdot150=900\), इसलिए धनात्मक (x=30)। मध्य पद ज्यामितीय माध्य होता है।
