    Try it with an example: The average of 12, 12, 12, 12 and 12 (5 numbers) is ...12! Now add 12. Average is still 12. Instead, add 60. Average is 120/6=20. Makes a lot of difference.

    If "x" is your 6th number, your average is:\[\frac{ 60 + x }{ 6 }\]This gives a real and useful answer, but of necessity has to be left in the form of a formula.

    In case that Latex didn't come through: (x + 60) / 6

    "60" is from: (x1 + x2 + x3 + x4 + x5)/5 = 12, so the sum is 60 for the first 5 numbers.
