Answer:
is a multiple of 4
Step-by-step explanation:
Let's think about this.
Even numbers are basically numbers that, when divided by 2, get us an integer.
This means that
must be an even integer.
<em>However,</em>
Every other even number, when divided by 2, gets you an odd integer.
This means that every second even number,
gets us an even number.
This also means that every time
is an even number, n will be a multiple of 4 (as
).
Test this out with any even number that's a multiple of 4 (all multiples of 4 are even numbers)
Hope this helped!
