Answer:
"x+1, x + 3"
Step-by-step explanation:
Consecutive even numbers' example would be:
2, 4, ...
16, 18....
212, 214...
What do they have in common?
They are spaced "2" units apart.
4 - 2 = 2
18 - 16 = 2
214 - 212 = 2
Now, let's check for the answer choices, whichever is "2" units apart, that is the one.
x + 2 -(x + 1) = x + 2 - x - 1 = 1 units
x+3 - (x+1) = x + 3 - x -1 = 2 units [this is the one]
2x + 1 - (2x) = 2x + 1 - 2x = 1 units
Hence, 2nd answer choice is representing consecutive even integers.
