Avg means we need to make every thing equal.
so first 4 days of the weeks are having -0.8. and last four days are having extra 1.2 so if we give 0.8 to first four days then they become 0( which is previously -0.8)
but still the last four numbers are having extra 0.4 so if the middle number is having 25.2 + 0.4 ,then only we can give that 0.4 to first four numbers and then all the numbers are having equal values. Thus we achieve the target to Average
