Create a data set that has five values. The mean of the data set should be 34.

250+20+20+10+40=34 this is the data set that would give u 34

Start with 34,34,34,34,34

minus 5 from 1 number and add 5 to another

29,34,34,34,39

minus 2 from a number and add 2 to another

29,32,36,34,39

minus 10 from a number and add 10 to another

19,32,36,44,39

repeat as many times as needed

basically

if the 5 numbers are x, y, z, t, a then

(x+y+z+t+a) / 5=34

times 5 both sides

x+y+z+t+a=170

just find 5 numbers that add to 170

100,20,20,20,5,5 is another one
