1. common ratio: The amount each consecutive term is multiplied by in a geometric
sequence.
2. pattern: A set of numbers or shapes arranged according to a rule.
3. addition: Finding the total of two or more values.
4. sequence: Numbers or shapes in a particular order.
5. difference: The result of one number being subtracted from another number.
6. odd number: An integer that is not even; any integers not divisible by 2.
7. arithmetic pattern: A set of numbers with a constant difference between consec-
utive terms.
8. 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.
9. operation: A mathematical calculation or process. The most common are addi-
tion, subtraction, multiplication, and division.
10. geometric pattern: A set of shapes with a repetitive order, also known as a
shape pattern.
11. subtraction: Finding the difference between values.
12. multiplication: An operation performed on two numbers that results in a prod-
uct. This operation is often denoted by the dot sign, ·.
13. set: A collection of things. In the context of math, these are usually collections
of numbers.
14. even number: An integer that is divisible by 2.
15. negative number: A number whose value is less than zero. On the number line,
these numbers are to the left of zero.
16. consecutive term: A term in a pattern or sequence that immediately follows
another term with no gaps between them.
17. ellipsis: A symbol made up of three dots (...) that is used at the end of a
sequence to indicate that the sequence is infinite, or goes on forever. Used in the
middle of a sequence, it indicates continuing.
18. shape pattern: A set of shapes with a repetitive order, also known as a geomet-
ric pattern.
19. positive number: A number whose value is greater than zero. On the number
line, these numbers are to the right of zero.
20. Unlike Term: A term that does not have the same variable(s) with the same
exponent(s) as another term. The terms cannot be combined using addition or
subtraction.
21. Exponent: Sometimes called a power, it is a number that shows how many times
the base is multiplied by itself. For example, the 3 in 8^3.
