यदि (4,x,64) गुणोत्तर श्रेढ़ी के लगातार धनात्मक पद हैं, तो (x) क्या होगा?
If (4,x,64) are consecutive positive terms of a geometric progression, what is (x)?
Explanation opens after your attempt
Correct Answer
A. (16)
Concept
\(x^2=4\cdot64=256\), so positive (x=16). The middle term is the geometric mean.
Why this answer is correct
The correct answer is A. (16). \(x^2=4\cdot64=256\), so positive (x=16). The middle term is the geometric mean.
Exam Tip
\(x^2=4\cdot64=256\), इसलिए धनात्मक (x=16)। मध्य पद ज्यामितीय माध्य होता है।
