The “ai” in the above sigma notation is saying that you sum all of the values of “a”. In other words, you’re adding up a series of values: a1, a2, a3,…, ax. i is the index of summation. It doesn’t have to be “i”: it could be any variable (j, k, x etc.)....
Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
Arithmetic sequences, the pattern of progressing numbers, can be classified by finding the difference between numbers in the sequence and then notating them into a formula. See the process of the two standard formulas used, as well as how to find them using terms. ...

What is a sum?The sum in mathematics refers to the result of adding two or more numbers or terms together. The sum can be expressed using summation notation, denoted by the Greek letter sigma (Σ). For example, 1+2+3+4+5 equals 15....
A flowchart is one of the most common types of workflow diagrams. It uses a series of symbols and arrows to depict the sequence of tasks and activities. Flowcharts are simple and intuitive, making them ideal for visualizing straightforward processes. They help identify the steps involved in a ...
