What's an Arithmetic Sequence?

Arithmetic and geometric sequences are linear and geometric patterns. Help pupils understand the relationship and see the connection with an activity that asks them to write the rules and classify the patterns correctly. A sorting...

Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

What comes next? Starting with concrete drawings and advancing to using function notation, learners work together to solve problems involving sequences. They predict the nth term in a sequence and write sequences in function notation.

Teach the class how to continue a given number pattern, and have them state a rule to explain their answer. Arithmetic sequences and related worksheets are used to reinforce the concept of numerical patterns using the nthterm.

2, 4, 6, 8, who do we appreciate? Do the numbers in this sequence make it an arithmetic sequence? Watch this video and find out.

To find the 20th term in an arithmetic sequence, use the secret formula. What secret formula? It's: a sub n equals a sub one plus parentheses n minus one close parentheses times d. Got that? No? The watch this video to learn about the...

Common difference? Sounds like an oxymoron. It's a math term used to describe a pattern that may occur between a series of numbers. Watch this video and the instructor will explain what the term means as it is applied to an arithmetic...

Briefly show your class or individual learners how to find the common difference in an arithmetic sequence. A quick and simple video, this resource should guide pupils toward understanding the concept of common difference. Appropriate...

Plain and simple, the common difference is a constant value that is added to a term in an arithmetic sequence. For example in the arithmetic sequence - 10, 20, 30, 40 É. - the common difference would be 10.
