Step 1
For the first term, we plug in \(n=1\): \[a_1 = 1^2 - 4 = 1 - 4 = -3\] For the second term, we plug in \(n=2\): \[a_2 = 2^2 - 4 = 4 - 4 = 0\] Show more…

Find the first four terms of the sequence. $a_{n}=\frac{n}{n^{2}+1}$
For the given recursively defined sequence, write the next four terms after the indicated initial term(s). $a_{n+1}=\frac{a_{n}}{a_{n-1}}, \quad a_{1}=1, \quad a_{2}=3$
