Consider a new sequence of five consecutive even numbers ending with 2a32a_32a3. If the sum of the numbers in the new sequence is 450450450, then a5a_5a5 isCAT 2022 Slot 1For any natural number n, suppose the sum of the first n terms of an arithmetic progression is (n+2n2)(n + 2n^2)(n+2n2). If the nthn^{th}nth term of the progression is divisible by 999, then the smallest possible value of nnn isCAT 2021 Slot 1The natural numbers are divided into groups as (1), (2,3,4),(5,6,7,8,9),….(2,3,4),(5,6,7,8,9), \ldots .(2,3,4),(5,6,7,8,9),….. and so on.
