What are Arithmetic and Geometric Sequences? A sequence is a group of numbers, called terms, arranged in a specific order. Arithmetic Sequences. Arithmetic sequences have a common difference. In other words the same value is added or subtracted from term to term. Example: 1, 3, 5, 7, 9, 11 (common difference is +2)
The Kelvin temperature scale is useful because scientists around the world use it as a temperature scale so that they don't have to convert Celsius to Fahrenheit or vise versa â¦ .
Scientists all over the world use the same system of units to measure physical quantities. This system is the International System of Units, universally abbreviated SI (from the French Le Systme International d'Units). This is the modern metric system of measurement.
