Understanding Arithmetic Sequences

This video tutorial explores arithmetic sequences, focusing on determining if a number is part of a sequence. It reviews the nth term rule, how to generate sequences, and how to find specific terms. The tutorial explains solving equations to check sequence membership, emphasizing that whole numbers indicate membership while decimals do not. Viewers are encouraged to practice with provided questions and are invited to engage with the content through comments and sharing.

What is the first step in determining if a number is part of a sequence?

• Check if the number is even.

• Substitute the number directly into the nth term rule.

• Make the nth term rule equal to the number.

• Divide the number by the first term of the sequence.
