I don't agree, at the end of first year, the loan is N less 12 paybacks, and you add the interests

ok else, to me, for the amount at beginning of years: $N_y = N_{y-1} - 12m + r(N_{y-1}-6m)$ no? (you have put $12m$ also multiplied by r)

seems x and y are mixed, it's V(x,b... ) above?

@AndréNicolas I thought when you do a loan, the interests were added at the end of the year only, but it's probably each months, it would increase slightly the result. yes r is the nominal interest rate (e.g. 2.5%), @ Limitless thx trying to understand it

@Shaktal $(n)_a$ is $\binom{n}{a} * a!$ like said in the ncmath's answer?

ah right (a,b) and (b,a) is the same unordered pair
