1) (2 points) Imagine a 21-gonal prism. How many total faces does this prism have? Provide a clear and detailed justification for your answer, using appropriate vocabulary, that does not rely on a

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?
