Value mart is having a back to school sale on pencils a pack of 30 sells for 7.97 whereas a 12 pack brand cost for 4.77 which is better to buy
and explain

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?
