Now i got my sequence u[n]=2*u[n-1]+1, no problem for the limit,
I tried
makelist(u[n],n,1,9);
to obtain u_1 to u_9. It does work. Is there another way? With map?
Is there a way to obtain the expression of u[n] in function of n with an defintion by recurrance?
example :
u_0=3
u_n=2*u_{n-1}
<verynycemaxymafunctioninordertoobtain:>
u_n=3*2^n
