Algebraic Sequence

Create the explicit formula for the sequence:

2, 8, 14, ...

(Hint: Write your formula and then simplify it.)

• y =2+6x

• y =-6+6x

• y =6x -4

• y=4-6x

Identify the common difference. (What do you have to do to get to the next term in the sequence?

97, 86, 75, 64, ...

• 8

• 11

• -11

• -8

Given the sequence:

25, 21, 17, 13,...

Write the equation that models the sequence.

• y = 4x + 29

• y = -4x + 25

• y = -4x + 29

• y = 4x + 25

The next two terms of the sequence 4,7,10,13 are ....

• 16 and 19
• 15 and 19
• 16 and 18
• 15 and 18

What is the 15th term of the sequence y = -3x+50

• 95

• -5

• 5

• -95

What is the 10th term of the sequence y = 20-2x

• 40

• -20

• 7

• 0

Find the common difference: 29, 21, 13, 5, ...

(How do you get from one term to the next?)

• d = -10

• d = -9

• d = -8

• d = -7

Which equation models the sequenece: 1, 201, 401, 601, ...

• y = 200x +1

• y = 1x + 200

• y = 200x - 199

• y = 1(200)^x-1
