Problem
State the first four terms of the sequence \( a_{n}=\frac{n+3}{n+4} \), starting from \( n=1 \). Write all four terms on the same line separated by a comma. \[ =\text { Enter your next step here } \]
Solution
Step 1 ：\( a_{1} = \frac{1+3}{1+4} = \frac{4}{5} \)
Step 2 ：\( a_{2} = \frac{2+3}{2+4} = \frac{5}{6} \)
Step 3 ：\( a_{3} = \frac{3+3}{3+4} = \frac{6}{7} \)
Step 4 ：\( a_{4} = \frac{4+3}{4+4} = \frac{7}{8} \)
