Explanation:

Question 2a


\text{Notice } 1=1^3, 8=2^3,\cdots, 125=5^3


\text{So the }n^{\text{th}} \text{ term is } a_n=n^3

Question 2b


\text{Notice the denominator is always larger than the numerator by 2, and the denominator of the }n^{\text{th}}\text{ is exactly }n.


\text{So the }n^{\text{th}}\text{ term is }a_n=(n+2)/(n)
