What is the general term equation, an, for the arithmetic sequence 5, 1, −3, −7, . . , and what is the 21st term of this sequence?
hint: an = a1 + d(n − 1), where a1 is the first term and d is the common difference.
an = 17 − 4n, a21 = −67
an = 17 + 4n, a21 = 101
an = 13 − 4n, a21 = −71
an = 9 − 4n, a21 = −75
