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

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

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

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 .

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.

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.

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(sequence;lower bound;upper bound;variable)

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