The weight of a sequence $a_0,a_1, \dots, a_{n-1}$ of real numbers is defined as $a_0+a_1/2+ \dots + a_{n-1}/2^{n-1}$. 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 ... $X$ is equal to $max(Y, a_0+Y)$ $max(Y, a_0+Y/2)$ $max(Y, a_0 +2Y)$ $a_0+Y/2$
