Find the nth and 1525th term for each of the following sequences

a.6, 4.8, 3.6, 2.4, 1.2, …

b.13, 11, 9, 7, 5,


3. Given the explicit formula for an arithmetic sequence find the first five terms and the term named in the problem.
nth = 65 − 100n. Find 39th term (To find the nth term, replace the n with 1, 2, 3, 4, 5 and 39)
Example : 1st term = 65 - 100(1) = -35
