Question

What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term of 3?
an = 5 − 3(n − 1); all integers where n ≥ 1
an = 5 − 3(n − 1); all integers where n ≥ 0
an = 5 − 2(n − 1); all integers where n ≥ 0
an = 5 − 2(n − 1); all integers where n ≥ 1
