ok so find the median so put the numbers in order so 82,83,84,85,85,86,86,86,87,87,88,89,90
then start from both sides cross off from both dies at the same time
83,84,85,85,86,86,86,87,87,88,89
84,85,85,86,86,86,87,87,88
85,85,86,86,86,87,87
85,86,86,86,87
85,86,86,86
86,86
so... 86 is the answer. i know its long but its the whole work hope it helped.
