For an arithmetic sequence, a_3 = -1 and a_12 = 44. Which option shows BOTH correct formulas (recursive and explicit)?
A
Recursive: a_1 = -11; a_n = a_(n-1) - 5; Explicit: a_n = -11 + 5(n - 1)
B
Recursive: a_1 = -11; a_n = a_(n-1) + 5; Explicit: a_n = -11 + 5(n - 1)
C
Recursive: a_1 = -11; a_n = a_(n-1) + 6; Explicit: a_n = -11 + 5(n - 1)
D
Recursive: a_1 = -11; a_n = a_(n-1) + 5; Explicit: a_n = -6 + 5(n - 1)
