70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140
the answer is 110. you go from both sides taking away one at a time until you meet in the middle. in this scenario two numbers were in the middle. i added 110 and 110 and got 220. at that point you divide by two.
to visualize this:
if the problem was like this
1, 2, 3, 4, 5
the median would be three because it’s in the middle. hope this helps!
