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.
{20, 25, 30, 35, ...} is also an infinite sequence. {1, 3, 5, 7} is the sequence of the first 4 odd numbers (and is a finite sequence) {4, 3, 2, 1} is 4 to 1 backwards. {1, 2, 4, 8, 16, 32, ...} is an infinite sequence where every term doubles. {a, b, c, d, e} is the sequence of the first 5 letters alphabetically.
