Though goals generally control objectives, objectives can also control goals as they unfold. For example, since a goal is general in nature, it may be refined and altered as objectives are completed. The completion of an objective or a series of them, could cause you to either raise or lower the ultimate goal.
For other uses, see Sequence (disambiguation). In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.
In mathematics, a (real) interval is a set of real numbers with the property that any number that lies between two numbers in the set is also included in the set. For example, the set of all numbers x satisfying 0 â¤ x â¤ 1 is an interval which contains 0 and 1, as well as all numbers between them. Other examples of intervals are the set of all real numbers R {\displaystyle \mathbb {R} } , the set of all negative real numbers, and the empty set.
