Algebra Arithmetic Sequence

Create the explicit formula for the sequence:
2, 8, 14, ...
(Hint:  Write your formula and then simplify it.)

• a_n=2+6n

• a_n=-6+6n

• a_n=6n-4

• a_n=4-6n

Is the sequence arithmetic: 37, 31, 25, 19, ...

• Yes

• No

Identify the common difference.
97, 86, 75, 64, ...

• 8

• 11

• -11

• -8

Find the common difference: -18, -23, -28, -33, ...

• d = -5

• d = 5

• d = -3

• d = 3

Is the sequence arithmetic: -3, 3, -3, 3, ...

• Yes

• No

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
