Dear my friend

I have the following function that I want to formulate in gams , could you please giude me how could I formulat it?

num=sum(from i=1 to i=T-k) , (1+r)**i

T=5

K={1,2,3,4}

after solve I need the following outputs

for k=1 (1+r)^1+(1+r)^2+(1+r)^3+(1+r)^4

for k=2 (1+r)^1+(1+r)^2+(1+r)^3

for k=3 (1+r)^1+(1+r)^2

for k=4 (1+r)^1

thanks in advance

mohammad

mohammad, something along the lines of…

eqnum(k)… num(k)=e=sum(i$(ord(i) le (T-ord(k)),(1+r)**ord(i));

regards
