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¦ .
Itâs used by seismologists, geologists and scientists. They use it to compare the size of earthquakes where the Richter scale is not so accurate.The Moment Magnitude Scale is more precise. Itâs not based on instrumental recordings of an earthquake.
