Explicitly defined sequence
A sequence in which the kth term is given as a function of k.
In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .
Head minus tail (HMT) rule
An arrow with initial point (x1, y1 ) and terminal point (x2, y2) represents the vector <8x 2 - x 1, y2 - y19>
