Write a recursive function to RETURN the nth term from the following SERIES { 0, 0.5, 1.5, 3, 5, 7.5 } That is, the 0th term is 0, the 1st term is 0.5. HINT: Only the 0th term is required to handle the base case. The difference between each term depends on the previous RULE EXCEPTION: You may use multiplication operator on the recursive step for this one */ double myseries( unsigned long n );
