Let the numbers be x-4, x-2, x , x+2, x+ 4 and given sum of all 5 number is 5, which is 5x = 5 and meaning x is 1
So the list is -3, -1, 1, 3, 5
I) AM of the list is 1 not 5, so eliminate
II) median is 1, not 5 , so eliminate
III) range is 5 - -3=8, not 5, so eliminate

Answer is A, None

I solved this question by thinking of numbers to fit in. Since the question says consecutive odd integers, if I only think of positive numbers then there is no way I can get 5 by adding them. for example 1,3,5, 7 adding any combination of these doesn't yield 5. So the numbers should contain a negative number. Since the sum is 5 I can't go much far so I included -1 then tried to add them, none are adding up to 5 then I included -3 then voila I get a sum which is equal to 5 that is {-3,-1,1,3,5} now I inputted these numbers to the I,II and III options and none came up to be true. Hence the answer A

The average will be less than 5.
the median will be less than 5.
The range will be greater than 5.
