Well, if it's a polynomial nth term, then it will have an n^7 term, and very possibly an n^8 term as well. (Excel can regress up to n^6, but it only gave an approximation).

It will most probably be a very complicated formula and give a strange value for when n=7.
So that means that it's probably something a bit different.

no i mean like is there a rule that will fit it like a progession of some sort

eg 1, 3, 10, 16, 23, 36, ? , 64, ? , 100

wat is the nth term of those numbers?

plz help

If you compare it to squares then:

1  2   3   4   5   6   7   8   9   10
1  3  10  16  23  36   ?  64  83  100
0 -1  +1   0  -2   0   ?   0   +2   0

And those last numbers don't seem to fit a pattern.

But it is close to n[sup]2[/sup]

My silly method gets 50 for the answer, but it is not logical and is based off of data that is only relevant to me, such as the 100 people I have assigned to the numbers from 1 to 100.
In my silly method (not mathematical), all of the numbers are women, except for 100.
As for a real answer, I cannot provide one, sorry.
