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¦ .
Celsius is commonly used in the Metric System in normal temperatures, i.e., room temperature, fridge temperature, freezer temperature, etc. Kelvin is mainly used in extr â¦ eme temperatures like in the melting point of diamonds, or temperatures on planetoids and planets such as Pluto.
