Learn how to determine if a sequence is an example of an arithmetic sequence or not

The video tutorial explains how to determine if a sequence is arithmetic by checking for a common difference between terms. It highlights that if the difference is not consistent, the sequence is not arithmetic. The example used shows a sequence where the difference is not uniform, thus it is not an arithmetic sequence.

What is the key factor in determining if a sequence is arithmetic?

• The number of terms

• The common difference between terms

• The product of all terms

• The sum of all terms

In the example sequence, what is the difference between the first two terms?

• 2

• 1

• 0

• 3

What is the difference between the terms 3 and 4 in the sequence?

• 3

• 2

• 1

• 0

Why is the given sequence not considered arithmetic?

• The terms are not in order

• It has too many terms

• The terms are all the same

• There is no common difference between all terms

Which of the following sequences is arithmetic?

• 1, 2, 4, 8

• 2, 4, 6, 8

• 5, 10, 15, 25

• 1, 3, 6, 10
