Question 63

1. An even integer is any number that can be written as:
   ( 2m )   (here, ( m ) is any integer)
2. “Consecutive even” means the next even number right after it. To go from one even number to the next, we add:
   ( 2 )
3. So, the first even integer is:
   ( 2m )
4. The next consecutive even integer is:
   ( 2m + 2 )

Check with an example: If ( m = 5 ), then ( 2m = 10 ) and ( 2m + 2 = 12 ). These are two consecutive even integers.
