In a typical problem of this type you would be give a question like "The sum of an odd integer and the next odd integer is 16. What are the two numbers?"The trick is knowing that the next odd integer is the first number plus 2. If we call the first number x, then we can write an equation like this:x + x + 2 = 16The first x is the first integer, the x + 2 is the next odd integer. Solve for x and you get x = 7. So the two numbers are 7 and 9 (x + 2).
