Answer:
a.
= 
b. 
Step-by-step explanation:
a) When <em>n </em>is even, then it is divisible by 2. Because of this, you can write:
b) When <em>n </em>is odd, then <em>n - 1 </em> is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:
× 
× 
The answer is false. n^2 would become 6^2 which is equal to 36 not 12
10/5 has a value between 10/3 and 11/3
Drawing a number line would help for this problem
