Answer 1

Answer:

I hope this will help you :)

Answer 2

Step-by-step 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

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

$\text{So the }n^{\text{th}}\text{ term is }a_n=\frac{n+2}{n}$
