How is a series different from a sequence?

• A sequence is a multiplication of numbers, while a series is their sum

• A series is a list of numbers, while a sequence is their sum

• A sequence is a list of numbers, while a series is their sum

• A series is a multiplication of numbers, while a sequence is their sum

What does 'a' represent in the arithmetic sequence formula?

• The common difference

• The sum of the sequence

• The last term in the sequence
