Now what does x n-1 mean? It means "the previous term" as term number n-1 is 1 less than term number n. And x n-2 means the term before that one. Let's try that Rule for the 6th term: x 6 = x 6-1 + x 6-2. x 6 = x 5 + x 4. So term 6 equals term 5 plus term 4. We already know term 5 is 21 and term 4 is 13, so: x 6 = 21 + 13 = 34 Many RulesIn mathematics, a prime number is any whole number greater than one that has no positive factors other than one and itself. For example, the number 17 is prime, because its only factors are one and 17.Math Symbols. Math is all about numbers, symbols, and formulas. Math symbols are used for different purposes from one mathematical field to another. Using symbols to represent mathematical information makes it easier to understand expressions as these symbols show the relationship between quantities.In mathematics, the expression 3! is read as "three factorial" and is really a shorthand way to denote the multiplication of several consecutive whole numbers. Since there are many places throughout mathematics and statistics where we need to multiply numbers together, the factorial is quite useful. Some of the main places where it shows up are ...Boston Celtics (47) vs. Washington Capitols (38) – 85 points.

Basic math glossary-N define words beginning with the letter N. n: A letter than can be used to stand for an unknown number. Natural numbers: The number 1 and any other number obtained by adding 1 repeatedly. Negative exponent: An exponent that is less than 0. Negative integer: A whole number less than 0. The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B. More formally, x ∈ A ⋂ B if x ∈ A and x ∈ B. The complement of a set A contains everything that is not in the set A . The complement is notated A’, or Ac, or sometimes ~A.n Power. A superscripted integer (any whole number n) is the symbol used for the power of a number. For example,3 2, means 3 to the power of 2, which is the same as 3 squared (3 x 3). 4 3 means 4 to the power of 3 or 4 cubed, that is 4 × 4 × 4.
