Add them agnd get -22 therefor at least one must be negative
difference between the greaterst and the least is 50 that means that the smallest one is 50 away from the smallest one
so just find numbers that subtract to get 50 and are less than -22 so one example is -25 and 25 since 25-(-25)=25+25=50 then add them and get filler milddle numbers to add to -22 -25+25=0 therefor the other 2 numbers could be anything that adds to -22 and is less than 25 and greater than 25 numbers are -20 and -2
therefor numbers are -25,-20,-2,25 add -25+-20+-2+25=-22 subtract 25-(-25)=25+25=50 TADA
