The Series Calculator evaluates mathematical series by computing partial sums. It handles arithmetic sequences, geometric sequences, and custom series defined by a general term expression.
Enter the general term of your series, specify the variable, start index, and end index. The calculator evaluates each term and provides the partial sum along with individual term values.

A series is the sum of terms in a sequence. A finite series has a definite number of terms and always has a sum. An infinite series may or may not converge to a finite value.
Common series include arithmetic series (constant difference between terms), geometric series (constant ratio between terms), and p-series (sum of 1/n^p). Convergence tests determine whether an infinite series has a finite sum.
