I can't think of how to title the problem I'm having, but this is what the course is called. Complex being imaginary numbers, ie z = a + ic where i is the sqrt of -1.
So here is the question that I have no idea where to start with:
Construct a sequence {zn} which is bounded and for which the successive
terms get increasingly closer, but which is not convergent. In other words,
{zn} must satisfy:
(i) For some B > 0, |zn| < B for every n = 1, 2,...
(ii) For every n, |zn+2 - zn+1| < |zn+1 - zn|.
(iii) {zn} diverges.
Note that the inequality in (ii) is strict. Make sure to prove that your
sequence satisfies all three parts.
n is a subscript of z.
Thanks in advance.
