Understanding Sequences

This video tutorial introduces key sequence terminology, including arithmetic, triangular, Fibonacci, quadratic, and geometric sequences. It explains how to recognize and generate these sequences, highlighting concepts like common difference and common ratio. The video also provides practice problems and encourages viewers to explore further topics like the nth term in future videos.

What is each number in a sequence called?

• Factor

• Term

• Digit

• Element

What is the common difference in an arithmetic sequence?

• The sum of terms

• The difference between consecutive terms

• The ratio of terms

• The product of terms

What pattern do triangular numbers follow?

• They increase by a constant difference

• They form a square

• They form a triangle

• They decrease by a constant difference

How do you find the next term in the Fibonacci sequence?

• Subtract the last two terms

• Divide the last two terms

• Add the last two terms

• Multiply the last two terms

What is a unique feature of the Fibonacci sequence?

• It forms a triangle

• It forms a square

• It is linked to the golden ratio

• It has a constant difference

What is a quadratic sequence characterized by?

• A constant first difference

• A constant second difference

• A constant sum

• A constant ratio

In a geometric sequence, what is the term for the value you multiply by each time?

• Common sum

• Common difference

• Common ratio

• Common factor

What is the main difference between arithmetic and geometric sequences?

• Both use multiplication

• Arithmetic uses addition, geometric uses multiplication

• Arithmetic uses multiplication, geometric uses addition

• Both use addition

What will future videos explore regarding arithmetic sequences?
