What is an Arithmetic Sequence?
When you add or subtract to find the next number in a sequence.
What type of sequence is this?
1, 3, 5, 7, 9, 11
Arithmetic
Write the recursive equation for this sequence.
1, 3, 5, 7, 9, 11
Next = Previous + 2
Write the explicit equation for this sequence.
Term 1 = 1
1, 3, 5, 7, 9, 11
f(n) = 1 + 2(n-1)

What is a Geometric Sequence?
When you multiply or divide the next number in a sequence.
What type of sequence is this?
25, 20, 15, 10, 5
Arithmetic
Write the recursive equation for this sequence.
25, 20, 15, 10, 5
Next = Previous - 5
Write the explicit equation for this sequence.
Term 0 = 25
25, 20, 15, 10, 5
f(n) = 25 - 5n

What is the common difference?
The common difference is the number you add or subtract in an Arithmetic sequence.
What type of sequence is this?
6, 12, 24, 48, 96
Geometric
Write the recursive equations for this sequence.
6, 12, 24, 48, 96
Next = Previous * 2
Write the explicit equation for this sequence.
Term 1 = 6
6, 12, 24, 48, 96
f(n) = 6 * 2(n-1)

What is the common ratio?
The common ratio is the number you multiply or divide in a Geometric Sequence.
What type of sequence is this?
80, 40, 20, 10, 5
Geometric
Write the recursive equation for this sequence.
80, 40, 20, 10, 5
Next = Previous * (1/2)
or
Next = Previous ÷ 2
Write the explicit equation for this sequence.
Term 0 = 80
80, 40, 20, 10, 5
f(n) = 80 * (1/2)n
