Sequence Reinforcement

Sequence

Ab ordered Set of Numbers. Each number in the sequence is called a "term."

Multiple Choice

What is a term? 

• Each number in the sequence. 
• Each variable in the sequence. 
• Each number or variable in the sequence. 

Two types of Sequences

• Arithmetic: Each term has a common Difference. Add the same number to get each term

• Geometric: Each term has a Common Ratio. Multiply the same number to get each term

Multiple Choice

How is an arithmetic sequence found?

• By multiplying the same number to the previous term. 
• By adding the same number to the previous term.

Multiple Choice

How is an geometric sequence found?

• By adding the same number to the previous term.
• By multiplying the previous term by the same number. 

Finding next terms of arithmetic sequence

• Determine Common difference

• add the difference to the last term

Multiple Choice

Describe the relationship between the terms in the arithmetic sequence 
4, 8, 12, 16

• Subtracting 4 to the previous term
• Adding 4 to the previous term
• Multiplying by 2 to the previous term
• Dividing each term by 2

Multiple Choice

What are the next three terms in the sequence 4, 8, 12, 16

• 20, 24, 28

• 18, 20, 22

Finding the next terms in Geometric Sequence

• Determine the common ratio

• usually done by dividing the second and first term

Multiple Choice

Describe the relationship between the terms in the geometric sequence
2, 4, 8, 16

• Multiplying the previous term by 2. 
• Adding by 2 to the previous term. 
• Subtracting the previous term by 4
• Multiplying the previous term by 4

Multiple Choice

Determine the next 3 terms of the sequence 2, 4, 8, 16...

• 18, 20, 22

• 32, 64, 128

• 24, 32, 40
