Therefore calling factorial 2 returns 2 factorial 1 which returns 2 1 2. Begin casesa 1 3leftarrowgray text the first term is 3 a n a n-12leftarrowgray text add 2 to the previous term end cases. Determine if the sequence is arithmetic Do you add or subtract the same amount from one term to the next 2.
A recursive formula allows us to find any term of an arithmetic sequence using a function of the preceding term.
