Using the graph attached below, what are the common difference, the general term equation, and the 12th term of the arithmetic sequence?
Hint: asubn = asub1 + d(n − 1), where asub1 is the first term and d is the common difference.
OPTIONS:
A) d = −3, asubn = 3 − 4n, asub12 = −45
B) d = 4, asubn = 5n − 4, asub12 = 56
C) d = −5, asubn = 4 − 5n, asub12 = −56
D) d = −4, asubn = 5 − 4n, asub12 = −43
