यदि (x,20,100) गुणोत्तर श्रेढ़ी के लगातार पद हैं, तो (x) क्या होगा?
If (x,20,100) are consecutive terms of a geometric progression, what is (x)?
Explanation opens after your attempt
B. (4)
Concept
\(\frac{100}{20}=5\), so \(\frac{20}{x}=5\) and (x=4). Keep consecutive ratios equal.
Why this answer is correct
The correct answer is B. (4). \(\frac{100}{20}=5\), so \(\frac{20}{x}=5\) and (x=4). Keep consecutive ratios equal.
Exam Tip
\(\frac{100}{20}=5\), इसलिए \(\frac{20}{x}=5\) और (x=4)। लगातार अनुपात बराबर रखें।
