What are the explicit equation and domain for an arithmetic sequence with a first term of 3 and a second term of 5?

Group of answer choices

an = 3 + 2(n − 1); all integers where n ≥ 0

an = 3 + 6(n − 1); all integers where n ≥ 1

an = 3 + 6(n − 1); all integers where n ≥ 0

an = 3 + 2(n − 1); all integers where n ≥ 1
