The general term for an expansion is "series". A series is a sequence of terms that are added together to form a sum.
A finite expansion has a limited number of terms, while an infinite expansion has an unlimited number of terms. In other words, a finite expansion has an ending point, while an infinite expansion does not.
A series is represented using sigma notation, which is written as Σ. The variable below the sigma represents the starting term, while the variable above the sigma represents the ending term. The expression to the right of the sigma represents the terms being added together.
A geometric expansion is a series where each term is found by multiplying the previous term by a constant number, called the common ratio. This type of expansion can either be finite or infinite, and the common ratio must be consistent throughout the series.
The sum of a series can be found by using a specific formula, depending on the type of series. For example, a finite arithmetic series can be found by using the formula Sn = n/2(a1 + an), where n is the number of terms, a1 is the first term, and an is the last term. For infinite series, the sum can be found by taking the limit of the series as it approaches infinity.
