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!
Glad you asked this question! Over the years of working with my professor we learned that if phs= 5 (constant) times the j to the power of 2 you will get the formula or polynomialic equation. It quite fascinating and due to using his equation the answer in fact is "c". Cheers
