how to keep adding a varaible in a loop?

i have this code which i want to write in a loop because it has to go on for a 1000 or so and i dont know how to make a loop for this inverval

NASDAQ_low = [norminv(1-NASDAQ(1,1)) norminv(1-(AA(1,1)+AA(1,2))) norminv(1-(AA(1,1)+AA(1,2)+ AA(1,3))) norminv(1-(AA(1,1)+AA(1,2)+AA(1,3)+AA(1,4))) norminv(1-(AA(1,1)+AA(1,2)+AA(1,3)+AA(1,4)+AA(1,5)) .... and so on

i also want to do the same for this

exp^LIBOR *(1+X)/(1-X)^2 + exp^LIBOR *(1+X)/(1-X)^2 + (1+X)/(1-X)^3 + exp^LIBOR *(1+X)/(1-X)^2 + (1+X)/(1-X)^3+ (1+X)/(1-X)^4 + exp^LIBOR *(1+X)/(1-X)^2 + (1+X)/(1-X)^3+ (1+X)/(1-X)^4

(1+X)/(1-X)^5 + etc....

could anyone give me a clue?

thank you in advance

First one:

n=1;
suma=0
for n=1:1:1000
    AA(1,n)
    suma=AA(1,n)+suma;
    norminv=1-suma
n=n+1;
end

Second one:

k=2;
suma=0;
for k=2:1:1000;
part=exp^LIBOR *(1+X)/(1-X)^k;
suma=suma+part;
k=k+1
end
