In math, the term n of a sequence refers to the algebraic representation of any given term in the sequence. This contrasts with the specific values of named sequence terms such as the first term and second term.
Know MoreWhen analyzing sequences, it is helpful to determine the rule that governs how additional numbers in the sequence are derived from earlier ones. In the example sequence 20, 40, 60, 80, ..., each subsequent term increases by 20 from the previous one. The first term is 20, the second is 40, and the nth term is given by the formula x = 20 times n. By determining the value of the nth term, one can identify the values of terms that appear much later in the sequence without needing to rely on numerous repeated computations.

Full Answer >In mathematics, an array is a set of numbers or objects placed in rows or columns. Arrays are often used to represent multiplication or division.
Full Answer >In mathematics, the abbreviation "exp" stands for the word exponent. An exponent is a number placed after another number to indicate the power to which the former number is to be raised. The expression 5 exp 2, for example, means 5 raised to the second power or 5 x 5.
Full Answer >In mathematics the difference is the result of subtracting one number from another, and represents the operation of removing objects from a collection. Mathematicians use the term "difference," because it shows by how much the two numbers in the subtraction problem differ.
