Sequences and Summation

In Mathland, we learned about sequences and summation. A sequence can be infinite and or finite and that appellation pretty much sums up how they are. Numbers with an exclamation mark can also be known as factorials. A factorial is basically the number that is being factorized times all the integers lower than it to zero. For example: 4!=4x3x2x1. However, the factorial of zero is one due to some important reasons. Summation notation is a way one can sum up sequences when the upper limit, explicit formula, and lower limit are known. There are also many properties of summation notations. Below are summations notations and their properties.

  1. Thanks for labeling the summation notion and telling me what each letter or number is. This helped me get a better understanding of what it is. It was also helpful that you put an example of summation notion. This will help me understand how to do problems like these. Thanks again!
