Simplify the equation 8 + 3n = 20​

8 + 3n = 20
Take away 8 from both sides.
3n = 12.
Divide both sides by 3.
n = 4

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?
