What are the explicit equation and domain for an arithmetic sequence with a first term of 7 and a second term of 3?
an = 7 − 4(n − 1); all integers where n ≥ 1
an = 7 − 4(n − 1); all integers where n ≥ 0
an = 7 − 3(n − 1); all integers where n ≥ 1
an = 5 − 3(n − 1); all integers where n ≥ 0

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
