Question 11
Find the value of $a$ when $a-b$ is minimum. The paired sequences are shown in the table.
Reading for this practice question: minimize the signed value of a−b over the paired terms shown. The source does not state an absolute value or require the difference to be positive; those alternative readings lead to a different answer.
