B)
an = 3n - 3

C)
an = n - 5

D)
an = 3n - 5

Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
the general formula for the nth term in an arithmetic sequence is:
an = a0 + d(n-1) where a0 is the first term, n is nth, d is the difference
**************************************************************************
for our problem a0 is -2, d is 3
an = -2 + 3(n-1)
an = -2 + 3n -3
an = -5 + 3n
the answer is option D
