What is the missing number ?
I have searched for days but still no results, the only thing I noticed is this: $$4-2=2=2.1=2.(5-4)$$ $$19-11=8=2.4=2.(23-19)$$ $$3739-2243=1496=2.748=2.(4487-3739)$$ But it has nothing to do with the numbers at the end. I think it is the value of some polynomial $f(x)$ with many values of $x$. For example: $f(x)=\dfrac{1}{12}x^4-\dfrac{5}{6}n^3+\dfrac{47}{12}n^2-\dfrac{25}{6}n+2$, with the values of $x$ being $1, 2, 3, 4, 5$ respectively,$f(x)$ has values $1, 4, 9, 16, 27$ respectively
A simple rule that appears to have meaning: multiply the top two numbers in a column and subtract the third to get the fourth number. Final number: $8382090$.
