Which of the following sequences has a common ratio?
2, 4, 6, 8,
12, 4, 4/3,
y = 3x - 2
80, 67, 54, 41,

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?
