This is an arithmetic sequence since there is a common difference between each term. A1c a n-1 where c is the constant and r is the common ratio. Then the 8th term is.
Begingroup I think of the options presented so far this is the nicest in that.
Play this game to review Algebra I. For example if the common difference is 5 then each term is the previous term plus 5. Then the common difference is 4. Using the recursive formula we would have to know the first 49 terms in order to find the 50 th.
