Question

If n is odd, which represents the first consecutive even integer after n?
A n + 1
B n + 2
C 2n
D 4n

Answer 1

let's say n is some odd number like 9

so n = 9

what is "the first consecutive even integer after n" ?

Answer 2

first consecutive even integer means the first NEXT even number.
So if you had an odd number "n" such as 1, the first consecutive even integer would be 2 :)
If you had had an odd number n= 3, the first consecutive even integer would be 4 :D
In both cases, can you see that in order to get the first even consecutive integer, you 1 and "n"
So for the first example where n = 1, the first even consecutive integer is 2
Therefore in order to get 2, we would add 1 to n
If n = 1
USING n + 1 as our formula.
1 + 1 = 2 ( which is the first even consecutive integer)
Similarly if n = 3 and we used n + 1
3 + 1 = 4 ( which is also the first even consecutive integer)
