After messing about with the numbers unsuccessfully for a while, I plotted the points on a chart and the pattern became pretty clear. Then it was just a matter of using regresison to work out the variables.

How d u get to this polynomial
? (unless you made the q but in general how do u form the pnomial)

Yea, i made the question.. so i know the polynomial form of it
wow, you are pretty good... how did you get this one? I'm sure the pattern isn't that obvious when plotted on a graph. I even took out the first number to make it look less like a Fibonacci sequence

A large amount of it was luck to be honest. It was the type of thing I could of looked at for hours and not realised, but as it happens, it took about 2 mins.wow, you are pretty good... how did you get this one?

Plotting it on the chart, it looked to be in the form of of either e(x) or x^2.
The next clue was the occasion .5. Thinking that you're likely to get one from time to time if you divide a series of numbers by 2 and some happen to be odd, I multiplied everything by 2. From there it was pretty obvious they were fib^2...

can anyone explain how to for example get the 100th number
given a series , i understand that you have to derive a polynomial
of some sort. But how to do this?

you could plot the points on a graph to help find the polynomial...

How about this
31
239
1007
6935
14051
25639
100 th number anyone?
or maybe just the next 3

I'm fairly confident that you've not given us enough data points to define your equation...

Its a polynomial to the power of 5 or higher... i cant be bothered to work it out

I think it's a polynomial to the power 6 or higher. Given we have only 6 data points, impossible to predict future points exactly. Can estimate though...

Its actually polynomial of degree 4
there for 6 is enough
first time making a sequence
so just tell how many more i need to give
the pnomial was
10x^4+3x^3+12x^2+x+5
