When to use parentheses and Order of operations?
Grouping Symbols and Order of Operations. Three common types of grouping symbols—parentheses ( ), brackets [ ], and braces { }—are used to group numbers or variables (letters). The most commonly used grouping symbols are parentheses. Operations inside parentheses can be done before any other operations in order to simplify the problem.
How are the terms in a sequence generated?
Take the current term and add the common difference to get to the next term, and so on. That is how the terms in the sequence are generated. If the common difference between consecutive terms is positive, we say that the sequence is increasing. On the other hand, when the difference is negative we say that the sequence is decreasing.
