Let the sum of an infinite G.P., whose first term is a and the common ratio is \(r\), be 5 . Let the sum of its first five terms be \(\frac{98}{25}\). Then the sum of the first 21 terms of an AP, whose first term is \(10 a r\), nth term is \(a_{ n }\) and the common difference is \(10 a r^2\), is equal to:  📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
