Is the following sequence infinite or finite: 25, 21, 17, 13, 9, 5, 1

• infinite

• finite

select all the increasing sequences:

• 1,3,6,10,15,21, ...

• 0,1,-1,2,-2,3,-3, ...

• 12,23,34,45,56,67, ...

• -1,-2,-3,-4,-5,-6, ...

What do all sequences have in common?

• Their terms are numbers

• They can all be written as functions

• They either increase or decrease

Select the sequences that decrease by division:

• 1,1/2,1/4,1/8,1/16,...

• 10,5,0,-5,-10,...

• 800,600,400,200,...

• 64,16,4,1,1/4,1/16,...

What is the DOMAIN of a sequence?

• the term number

• 1,2,3,4,...

• hint: its the first two ;)

What is the RANGE of a sequence?

• the term number

• 5

• the value of the term (depends on the sequence)

Is the following sequence finite or infinite: 100,20,4,4/5,...

• finite

• infinite

Ms. Cooper creates a sequence of desks in her classroom. The first row has 4 desks, the second row has 5, the third row has 6, and so on. Is this sequence infinite or finite? why? (Hint: think of the context of the problem)

• Infinite, she can have as many desks has she wants

• finite, her classroom only has so much space

Select the sequence that matches this description: begins with a positive number, decreases by multiplication, is finite

• -5,-1,-1/5,-1/25, ...

• 27, 9, 3, 1, 1/3

• 22,11,11/2,11/4,...
