The sum of the elements of your set was 350

a , b , c , 50 , d , e , f

We removed one of the elements and the median was still 50. The only way that's possible (since all of the elements are distinct) is if we remove 50 and the average of c and d is 50

(c + d) / 2 = 50

c + d = 100

a , b , c , 50 , d , e , f

c + d + 50 = 150

a + b + c + 50 + d + e + f = 350

a + b + e + f + 150 = 350

a + b + e + f = 200

If a and b are 1 and 2

1 + 2 + e + f = 200

e + f = 197

The minimum value for e is 52 (since the minimum value of d is 51)

52 + f = 197

f = 145

The greatest value possible in the set is 145
