Non-Repeating Number Patterns

The video tutorial introduces the concept of patterns in sequences, explaining both repeating and non-repeating patterns. It provides examples of number patterns, demonstrating how to identify the rule governing a sequence. The first example shows a pattern starting with 3 and adding 3, while the second example starts with 5 and adds 2. A third example illustrates a pattern starting with 90 and subtracting 4. The lesson emphasizes understanding the rule behind a pattern to generate further numbers in the sequence.

What is the next number in the sequence 3, 6, 9, 12?

• 13

• 14

• 15

• 16

If a pattern starts with 5 and each subsequent number is increased by 2, what is the fourth number in the sequence?

• 11

• 10

• 12

• 9

What is the rule for the number pattern that starts with 5 and continues as 5, 7, 9, 11?

• Start with 5, subtract 2

• Start with 5, add 2

• Start with 5, subtract 3

• Start with 5, add 3

In a sequence starting with 90 and decreasing by 4 each time, what is the third number?

• 78

• 74

• 82

• 86

What is the rule for the sequence that starts with 90 and continues as 90, 86, 82, 78?

• Start with 90, add 4

• Start with 90, subtract 4

• Start with 90, subtract 3

• Start with 90, add 3
