यदि (36,x,100) धनात्मक गुणोत्तर श्रेढ़ी के लगातार पद हैं, तो (x) क्या होगा?
If (36,x,100) are consecutive terms of a positive geometric progression, what will (x) be?
Explanation opens after your attempt
C. (60)
Concept
\(x^2=36\cdot100=3600\), so positive (x=60). The square of the middle term equals the product of the outer terms.
Why this answer is correct
The correct answer is C. (60). \(x^2=36\cdot100=3600\), so positive (x=60). The square of the middle term equals the product of the outer terms.
Exam Tip
\(x^2=36\cdot100=3600\), इसलिए धनात्मक (x=60)। मध्य पद का वर्ग बाहरी पदों के गुणनफल के बराबर होता है।
