### Function : sequence

#### Summary :

Sequence calculator allows to calculate online the terms of the sequence whose index is between two limits.

Sequence online

#### Description :

The sequence calculator is able to calculate online the terms of a sequence between two of the indices of this sequence.

## Calculating the terms of a suite

The calculator is able to calculate the terms of a sequence between two indices of this sequence.

Thus, to obtain the elements of a sequence defined by u_n=n^2 between 1 and 4 , it is necessary to enter : sequence(n^2;1;4;n) after calculation, the result is returned u_1=1 ; u_2=4 ; u_3=9 ; u_4=16.

The sequences can also be calculated by recurrence, for that, it is necessary to use the the calculator of sequences defined by recurrence .

## Calculation of elements of an arithmetic sequence

The calculator allows to calculate the terms of an arithmetic sequence between two indices of this sequence

Thus, to obtain the terms of an arithmetic sequence defined by u_n=3+5*n between 1 and 4 , enter : sequence(3+5*n;1;4;n) after calculation, the result is returned.

## Calculation of the terms of a geometric sequence

The calculator is able to calculate the terms of a geometric sequence between two indices of this sequence.

Thus, to obtain the terms of a geometric sequence defined by u_n=3*2^n between 1 and 4 , enter : sequence(3*2^n;1;4;n) after calculation, the result is returned.

## Calculation of the sum of the terms of a sequence

The calculator is able to calculate the sum of the terms of a sequence between two indices of this series, it can be used in particular to calculate the partial sums of some series. .

Sequence calculator allows to calculate online the terms of the sequence whose index is between two limits.

#### Syntax :

sequence(sequence;lower bound;upper bound;variable)

#### Examples :

sequence(n^2;1;4;n), returns u_1=1 ; u_2=4 ; u_3=9 ; u_4=16.
