You can put this solution on YOUR website! this is an Arithmetic Sequence because the difference between one term and the next is a constant, and equal to
in general we could write an arithmetic sequence like this:
{ , , , , ... }
(the first term) (the "common difference" between terms)
as a rule for any term: => we use "n-1" because d is not used in the 1st term
and calculate the 75th term
