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 2021 Slot 3Consider a sequence of real number x1,x2,x3,...x_1, x_2, x_3, ...x1,x2,x3,... such that xn+1=xn+n−1x_{n+1} = x_n + n - 1xn+1=xn+n−1 for all n≥1n \ge 1n≥1. If x1=−1x_1 = -1x1=−1 then x100x_{100}x100 is equal toCAT 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. Then, the sum of the numbers in the 15th group is equal to
