Arithmetic Sequences - Algebra 1

Find the common difference: -34, -29, -24, -19, ...

• d = -5
• d = 5
• d = -6
• d = 6

Find the next three terms in the arithmetic sequence: -33, -24, -15, -6, ...

• -1, 7, 15
• -5, 2, 9
• 3, 12, 21
• -65, -73, -81

Find the 35th term in the arithmetic sequence: -10, -14, -18, -22, ...

(Hint: Write the explicit rule first, then use it to solve)

• -216

• -148

• -146

• -150

Create the explicit formula for the sequence:

2, 8, 14, ...

• y = 2 + 6x

• y = -6 + 6x

• y = 6x - 4

• y = 4 - 6x
