OpenStudy (ram231):

pooja195 (pooja195):

Now that you gave the answer explain it :-)

OpenStudy (ram231):

I did. all you have to do is add ALL the numbers up... and then divide by the amount of numbers there are. so since there are 6 numbers, you have to divide by that number.

pooja195 (pooja195):
