Final answer:
A sequence is a set of ordered elements, and a series is the sum of those elements in a sequence, with option a) representing the correct description of the difference between them.
Step-by-step explanation:
The difference between a sequence and a series is fundamental in mathematics, particularly in the study of calculus and discrete math. Option a) accurately describes the difference between the two concepts.
A sequence is a set of ordered elements. For example, the natural numbers 1, 2, 3, ... form a sequence because there is an order to the elements, and each element has a specific position within that set.
A series, on the other hand, represents the sum of elements in a sequence. Using the previous example of natural numbers, if we were to add them together (1 + 2 + 3 + ...), the result would be a series.
