Answer:
b. x + 1, x + 3
Step-by-step explanation:
Integers : a number with no fraction part is called integers,
eg: ......-3, -2, -1, 0, 1, 2, 3......
Even integers : the integers which are multiple of 2.
Since, the difference between two consecutive even integers is always 2.
Eg : 2 and 4 are consecutive even integers.
⇒ 4 - 2 = 2.
∵ x + 2 - (x + 1) = x + 2 - x - 1 = 1,
x + 3 - (x+1) = x + 3 - x - 1 = 2,
2x + 1 - 2x = 1,
Hence, only x + 1 and x + 3 represent consecutive even integers
