This question is a real sequence-buster! I'm tempted to say E) -10, just to see the look on the examiner's face.

I'm going to go with A) 0. Why not? Sequences can be a bit unpredictable sometimes, so 0 seems like a good answer to throw off the competition.

Hmm, this is tricky. I'm leaning towards C) 10, because the CACHE 10 parameter means the sequence will pre-allocate 10 values at a time.

I believe it's D) 11, since the sequence will cycle back to the beginning after reaching the maximum value.

I think it's B) 1, because the sequence starts at 1 by default.

I think the answer is A) 0 because the sequence starts at 0 and cycles after reaching the maximum value.
