What is an Arithmetic Sequence?
They are sequences where each term is a fixed number larger than the term before it.
Set
A collection of things. In the context of math, these are usually collections of numbers.

Subtraction
Finding the difference between values.
Arithmetic Pattern
A set of numbers with a constant difference between consecutive terms.
Ellipsis
A symbol made up of three dots (…) that is used at the end of a sentence to indicate that the sequence is infinite, or goes on forever. Used in the middle of a sentence, it indicates continuing.
Difference
The result of one number being subtracted from another number.
Pattern
A set of numbers or shapes arranged according to a rule.
Common Ratio
The amount each consecutive term is multiplied by in a geometric sequence.
Positive Number
A number whose value is greater than zero. On the number line, these numbers are to the right of zero.
Geometric Partern
A set of shapes with a repetitive order, also known as a shape pattern.
Term
An individual number or variable, or numbers and variables multiplied together in an expression, separated by addition, +, subtraction, -, or division, /, signs. Numbers or variables separated by an operation symbol or equal sign.
Negative Number
A number whose value is less than zero. On the number line, these numbers are to the left of zero.
Operation
A mathematical calculation or process. The most common are addition, subtraction, multiplication, and division.
Sequence
Numbers or shapes in a particular order.
Odd number
An integer that is not divisible by 2.
Addition
Finding the total of two or more values.
Consecutive Term
A term in a pattern or sequence that immediately follows another term with no gaps between them.
Multiplication
An operation performed on two numbers that results in a product. This operation is often denoted by the dot sign, • .
Even number
An integer that is divisible by 2.
