Define the CYCLE/NO CYCLE into a Sequence

Question

Define the CYCLE/NO CYCLE into a Sequence.

Answer 1

CYCLE means that the sequence continues to generate values after reaching either minimum or maximum value. After pan-rising sequence reaches its maximum value, this generates minimum value of it. After a downward sequence reaches its minimum, this generates its maximum.

NO CYCLE means that the sequence can’t produce more values after reaching its minimum or maximum value.
