If (5,x,y,20) are consecutive terms of an arithmetic progression, what will be the values of (x) and (y)?यदि (5,x,y,20) अंकगणितीय श्रेणी के क्रमागत पद हैं तो (x) और (y) के मान क्या होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x=10,y=15)(x=10,y=15)
There are three equal gaps from (5) to (20), so (d=\frac{20-5}{3}=5), hence (x=10) and (y=15). Find missing terms by splitting the total difference into equal gaps.(5) से (20) तक तीन समान अंतर हैं इसलिए (d=\frac{20-5}{3}=5), अतः (x=10) और (y=15)। दो पदों के बीच समान अंतर बांटकर खाली पद निकालें।
