Patterns and Sequences in Mathematics

The video tutorial introduces the concept of patterns, including terms and term numbers. It covers three types of patterns: growing, shrinking, and repeating. Growing patterns are explained with examples using addition and multiplication. Shrinking patterns are demonstrated with subtraction. Repeating patterns are discussed with a focus on identifying core patterns. The video concludes with a summary and an invitation to take a quiz.

What is a term in a pattern?

• A number that repeats

• A number that is always the same

• A number that is part of a sequence

• A number that is not part of a sequence

How do you determine the term number of a pattern?

• By multiplying the terms

• By subtracting the terms

• By adding all the terms

• By counting the position of the term in the sequence

In a growing pattern, if each term increases by 11, what is the 8th term if the 7th term is 77?

• 66

• 77

• 88

• 99

If a pattern is defined by multiplying the term number by 11, what is the 9th term?

• 77

• 88

• 110

• 99

In a pattern where each term is obtained by adding 2 to the previous term, what is the 8th term if the 7th term is 14?

• 22

• 20

• 18

• 16

In a shrinking pattern, if each term decreases by 10, what is the 8th term if the 7th term is 30?

• 40

• 30

• 20

• 10

What is the next term in a shrinking pattern where each term decreases by 7, starting from 7?

• 1

• 0

• 3

• 2

In a repeating pattern of 2, 4, 6, what comes after 4?

• 8

• 6

• 4

• 2

What is the core pattern in a repeating sequence of 2, 4, 6?

• 2, 4

• 4, 6

• 2, 4, 6

• 6, 2

How do you identify a repeating pattern?

• By finding the term that is different

• By identifying the sequence that repeats

• By counting the number of terms

• By adding all the terms
