You do not need to call one of your even numbers with = an integer to show that it is an even number.
You can call one of those 6 even numbers , and when you solve for , check if it is an even number. If the you find is not even, there is no solution.
One option is = the smallest of the 6 consecutive even numbers.
If you learned about arithmetic sequences, you can try to use some formulas from that, but it may be more trouble than it's worth.
If the smallest even integer is , the other 5 even numbers are , , , , and .
The sum is
