All even numbers are multiples of 2. Therefore, 2k is an even number.
As we all know that the sum of an even number and an odd number is always an odd number, so 2k+7 is an odd number.
Verification...
If the value of k =1
we get 2k+7=9
If the value of k=2
we get 2k+7=11
In this way 2k+7 is always an odd number.
Hope it is clear enough to understand and helpful.... ^_^
