The number game

Ok, new pattern...

86.5,
115 1/3,
259.5,
230 2/3,
432.5,
346,
605.5,
461 1/3... what are the next 2 numbers, you wont find the answer for this one on google :
Are the next numbers 778.5, 576 2/3, 951.5 & 692?
 
wow... how did you work that one out??
*yes, it was right

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

578 1512.5 3960.5 10368 27144.5

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.

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...
 

genius much?
 
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
 
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
