Enter any two positive numbers, one for $a_1$ and another for $a_2$. Perform the iterations $a_{n+2}=\frac{a_{n+1} +1}{a_n}$ until you find values for the next five terms in the sequence.

Do the two starting numbers need to be positive? Are there any numbers that can not be used as starting numbers? Does the pattern in the iteration above always hold?
