Question:-
The weight of a sequence a0, a1,.....,an-1 of real numbers is defined as a0 + a1 / 2 + .... + an-1 /2n-1 A subsequence of a sequence is obtained by deleting some elements from the sequence, keeping the order of the remaining elements the same. Let X denote the maximum possible weight of a subsequence of
A0,a1 ,....,an-1. Then X is equal to
Option (A)
max (Y, a0+ Y)
Option (B)
max (Y, a0+ Y /2)
Option(C)
max (Y, a0+ 2Y)
Option(D)
a0 + Y/2
