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

What is the rule (explicit equation) for the n^th term given 
60, 55, 50, 45, ...

• a_n= -5+60n
• a_n= -5n+55
• a_n= -5n+65
• a_n= 5n+55

Write the explicit rule for the arithmetic sequence
-10, -3, 4, 11,...

• a_n = 10n + 17
• a_n = 7n - 17
• a_n = -7n + 17
• a_n = 7n + 3

Write the explicit rule for the arithmetic sequence
9, 13, 17, 21, ...
