I want to find the avg of 50 numbers. How can I do?

I learnt that in 5th grade, I beleive?

Sir Isaac Newton first asked this question, but was unable to give a satisfactory answer. Einstein also tried without success.

Rumour has it that Fermat's Last Theorem includes the answer but has long been lost.

Fermat's last theorem was proved by Andrew Wiles, the British mathematician. It all lies in the enumeration of ellipitical equations. So, it all in the curve.

You misunderstood Matt:

Fermat also claimed to have solved his "last" theorem, but neglected to publish it. In his notes that only I have, he also includes a method of finding averages.

Rob

[matt]

Fair enough.

Wiles' proof was just a codicil to his major theorem that was well over a hundred pages. There have been times when a complicated long proof has been replaced with a half page proof.

So when you publish Fermat's notes, you'll be very rich.

Anyway - you should really hand them over to me. After all, they're fer matt....

Arithmetic mean ?

or

Geometric mean ?

or

Hamonic mean ?

Or the mode or the median or the skew or kurtosis...

[Former Member]

Oops, I had to check the Wiki. My English technical vocabulary is not so advanced !

Mode (statistics), the value that has the largest number of observations

a median is described as the numeric value separating the higher half of a sample.

Skew normal distribution, a continuous probability distribution that generalises the normal distribution to allow for non-zero skewness

Kurtosis : "peakedness" of the probability distribution of a real-valued random variable

Enter them into a (newer) Excel version, mark them, check the status line.

Or do it like a senior consultant: Make a smart face, act self-confident and come up with any number. Nobody will doubt it.

N*(N+1)/2N

..........if these are serial nos.....

Expanding on Nick 's suggestion:

One N may be canceled:

(N+1)/2

..........if these are serial nos.....

..........and starting from 1

[matt]

Sort the numbers. Take the 25th.

The logic is same in all the languages.

Pl check out the syntax and try.

[matt]

Multiply them all together then take the 50th root.
