If (a_n=5\cdot4^{n-1}), what is the value of (\frac{a_7}{a_4})?यदि (a_n=5\cdot4^{n-1}) है, तो (\frac{a_7}{a_4}) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (64)(64)
(\frac{a_7}{a_4}=r^3=4^3=64). In the same progression, the ratio of terms depends on the difference of positions.(\frac{a_7}{a_4}=r^3=4^3=64)। समान श्रेढ़ी में पदों का अनुपात पद-संख्या के अंतर पर निर्भर करता है।
