How does the mean of the data set below change if each value is increased by 8?

Suppose our data set is:
2,4,6,8
the mean of the above data is:
(2+4+6+8)/4=20/4=5

Increasing the above value by 8
10,12,14,16
the mean will be:
(10+12+14+16)/4
=52/4
=13
The difference in the two mean values i
13-5=8
Thus we conclude that if we increase our values by 8, the mean increases by 8
