16. A constant that a variable or expression is multiplied by.
17. A collection of related measurements.
18. An expression that is multiplied by another expression, or that can be multiplied by another expression to produce a specified result.
19. A mathematical sentence with an equals sign (like 3x+5=11).
20. terms that have the same variable raised to the same power.

2. A sequence of numbers in which each number can be computed by adding the same amount to the previous number.
