GMAT Quantitative Reasoning Practice Test 1

The next larger multiple of two would be $\mathit{x}-3+2$, which is $\mathit{x}-1$.In this case, remember that any even number is a multiple of two and all evens are two numbers apart. If $\mathit{x}-3$ is a multiple of two, you can assume that it is also an even number. This number plus two would also produce an even number.
