How to determine if an sequence is arithmetic or not

The video tutorial explains how to determine if a sequence is arithmetic by checking for a common difference between terms. It provides examples to illustrate the process and concludes that if no common difference is found, the sequence is not arithmetic.

What is the first step in determining if a sequence is arithmetic?

• Check if all terms are even

• Look for a common difference between terms

• Ensure all terms are positive

• Verify the sequence is finite

What confirms that a sequence is arithmetic?

• All terms are prime numbers

• The sequence has a common ratio

• There is a common difference between terms

• The sequence is infinite

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

• 11

• 3

• 0

• 2

Why is the sequence in the example not considered arithmetic?

• It has a common difference

• All terms are equal

• It is a geometric sequence

• There is no common difference

What is the difference between the second and third terms in the example?

• 11

• 0

• 3

• 2
