Question 996879: To package and ship an item, it costs $6.25 for the first pound and $1.25 for each additional pound. Find the 9th term? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Here the sequence is
a-sub-n = 6.25 + 1.25(n-1)
so that
a-sub-9 = 6.25 + 1.25(9-1) = 6.25 + 10
a-sub-9 = 16.25
