There are two main ways to approach these kinds of problems: brute-force or using a formula. The latter is what we use here, but it is really easy to use a formula when you know what you’re doing. The former is a bit more involved but it is much more tedious.

I know you probably already know that the sum of two consecutive even numbers is 2 and the sum of two consecutive odd numbers is 3, but the formula doesn’t explain that. It takes a bit of algebra to work out, but we can get it down to a formula in our heads. The sum of two consecutive odd numbers is, of course, 4, but the formula tells us that the sum of the evens is, of course, 6.

So what does the formula do? It tells us that the sum of two consecutive even numbers is 2. That means that there was a 1 in the sum of the first number and a 0 in the first number. The sum of the evens is, of course, 6.

The formula tells us that the sum of two consecutive even numbers is 4. That’s wrong. It means that the sum of the odds is 4. We just don’t know how many odds there are, but it doesn’t matter.
