If (5,,\Box,,45,135,\ldots) is a geometric progression what term fills the blank?यदि गुणोत्तर श्रेणी (5,,\Box,,45,135,\ldots) है तो रिक्त स्थान में कौन-सा पद होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (15)(15)
The ratio of (45) and (135) is (3) so the missing term is (45\div3=15). In exams apply the ratio backward too.(45) और (135) का अनुपात (3) है इसलिए रिक्त पद (45\div3=15) है। परीक्षा में पीछे की ओर भी अनुपात लगाएँ।
