Question

"If an integer n is odd, then n+1 must be even."

Answer 1

Yes

Explanation:

for example

n = 3. odd

n + 1 = even

3 + 1 = 4

4 (even number)

Answer 2

True.

Explanation:

Let me clear it to you by an example:

if you take n=1,3,5,7,...... which are odd numbers

then adding 1 with them will give you n+1=2,4,6,8.... which are even numbers.

That's how, if an integer n is odd, then n+1 must be even.

Similarly, if you let n as even numbers, then n+1 will be odd.
