What is the difference between a sequence and a series?
a. a sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
b. a sequence is an unordered list of numbers whereas a series is the sum of a list of numbers.
c. a series is an unordered list of numbers whereas a sequence is the sum of a list of numbers.
d. a sequence is an ordered list of numbers whereas a series is an unordered list of numbers.

A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.

Step-by-step explanation:

Sequence: The collection of ordered list of numbers are called sequence. The numbers of the ordered list are called elements or terms.

Series: When we add the elements of the sequence then it is said to be series.

Let us understand these examples from the below example.

The numbers 2, 4, 6, 8, 10is called sequence. the difference between two consecutive terms is 2 and hence it is an arithmetic sequence.

And when we add the elements  2+ 4+ 6+ 8+ 10 the it is called an arithmetic series.

Looking into the options,2, 4, 6, 8, 10

d. vertex
