Patterns and Sequences in Mathematics

The video tutorial introduces number patterns, explaining how to create and identify pattern rules. It covers examples of growing and shrinking patterns using addition, multiplication, and subtraction. The tutorial also includes application questions to reinforce understanding and concludes with a call to action for further engagement.

What is the rule for the pattern that starts with 3 and grows by adding 3 each time?

• Start at 3 and multiply by 3 each time

• Start at 3 and subtract 3 each time

• Start at 3 and add 3 each time

• Start at 3 and add 2 each time

If the pattern rule is to multiply the term number by 3, what is the 4th term?

• 9
