    Since the middle numbers are 25 and 38, you need to find the number exactly in the middle of both of them to find the median,

  • step 1:

    x=the missing value

    the median is the middle number, but in this case there are two which happens to be 25 and x

    so the formula is

    25+x/2=31.5

    use algebra to solve

    25+x=63

    x=63-25

    x= 38

    the missing value is 38

  • the missing value is 38 because you take the median which is the 2 middle numbers added together then divided by 2. so to reverse it to find the answer you take 31.5 *2 and it come out as 63.

    now we subtract 25 from 63 like 63-25 = 38. 38 is your answer.
