Answer:
Explanation:
Let n be an integer
Given that 
is odd
To prove that n is even
a) Proof by contraposition
Let be non odd
Then this would be a multiple of 2 being even
i.e. we get cube of n is odd since gives remainder 1 when divided by 2
It follows that n is odd.
Thus proved by contraposition
b) contradiction method:
If possible let is odd for n odd.
Then we get
since n is odd,
is odd being the product of three odd numbers
When we add 5, we get
is even being the sum of two odd numbers
A contradiction
Hence our assumption was wrong
if n is an integer and n^3 + 5 is odd, then n is even
