The mean will increase and the median will change.  Do you know how to calculate the mean and find the median?  This is pretty simple, but if you are not familiar with the subject, read this:  www.purplemath.com/modules/meanmode.htm

median is the middle value.   from these numbers:

1 2 4 6 7, 4 is the middle value, so that is the median

oh thanks i was kind  of confuse  I will check that site out

anonymous · Answer

the mean is the useful average, 1+2+4+6+7 = 20

20 divided by 5 is 4, that is the average (mean)
