Question 121478
notice that the difference of any two consecutive even (or odd) integers is always 2. evidence----2 and 4 are consecutive even integers and 4-2=2.

So, if x is the smaller number, then x+2 is the larger number

And, their sum is

x+(x+2)

Given that the sum of two consecutive even numbers is 622, then

x+(x+2)=622
(x+x)+2=622
2x+2=622
2x+2-2=622-2
2x+0=620
2x=620
x=310

As expected, x is an even number

So,
x+2=310+2=312


Thus,
if the sum of two consecutive even numbers is 622, then the numbers are 310 and 312.
