Let a1,a2,a3,… be a sequence of positive integers in arithmetic progression with common difference 2. Also, let b1,b2,b3,… be a sequence of positive integers in geometric progression with common ratio 2 . If a1=b1=c, then the number of all possible values of c, for which the equality 2a1+a2+…+an=b1+b2+…+bn holds for some positive integer n,is π²PW App Link - https://bit.ly/YTAI_PWAP πPW Website - https://www.pw.live
