hi...this is the problem:
lim (ri)^n , when n -> infinite, i*i=-1 and r>0

thank you

Isn't it obvious that itself goes to infinity so there is no limit?

In fact, even if r= 1, this sequence is i, -1, -i, 1, i, -1, -i, 1, ... and so does not converge.

If then it converges to 0.

thank u so much for your answer.
