If in an AP (a_5+a_9=60) and (d=3), what is (a_7)?यदि किसी AP में (a_5+a_9=60) और (d=3) है, तो (a_7) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (30)(30)
In an AP, the average of equally spaced terms is the middle term, so (a_7=\frac{60}{2}=30). For symmetric terms, the average method is faster.AP में समान दूरी वाले पदों का औसत बीच वाला पद होता है, इसलिए (a_7=\frac{60}{2}=30)। सममित पदों में औसत विधि तेज होती है।
