Let the number be a, b , c and d in increasing order.
Is (a+d)/2>(a+b+c+d)/4.......4a+4d>2a+2b+2c+2d.....a+d>b+c
(1) The difference between the largest and the second largest numbers is greater than the difference between the second smallest and the smallest numbers.
So d-c>b-a......a+d>b+c
Sufficient
(2) The difference between the largest and the second largest numbers is less than the difference between the second largest and the second smallest numbers.
d-c<c-b...b+d<2c
Just tells us that c is greater than average of b and d
Insufficient
