Algebra: Chapter 3-11 (p 158)
More Expressions and Equations
Remember, the sum of an integer and the next integer can be represented by `x` and `(x+1)` or `x+ (x+1)`. The sum of consecutive (comes right after each other) odd OR even integers can be expressed as `x` and `(x+2)` or `x + (x+2)`. If you get confused, just make a little table, like 3, 4, 5, 6, 7 and 8 and see where the variable `n` would line up if the numbers were hidden.
Here is a link that shows a few examples too.
