Sequence —— (sequ)

This command creates the function that describes the relationship between the
variable and the value of the expression, if the value of the expression is entered
when the variable is assigned the first specified , the second specified
, and so on.

• The function is a linear algebra expression.

Syntax 1: sequence ({, , ...} [,] [)]

• A default variable of X is used when specification of a variable is skipped.

Example

To obtain the expression when 1 through 4 is {23, 30, 37, 45}

• If List 1 = {23, 30, 37, 45}, the same result can be obtained by inputting the

following: sequence(List 1, N).

Syntax 2: sequence ({, , ...},{, , ...} [,] [)]

The values input with this syntax are handled as lists, with the first value of the
first list paired with the first value of the second list, the second value with the
second value, and so on. This syntax creates a function using this relationship.

Example

To obtain an expression for variable values {2, 4, 6, 8} and
expression values {23, 30, 37, 44}

• If List 1 = {2, 4, 6, 8} and List 2 = {23, 30, 37, 44}, the same result can be

obtained by inputting the following: sequence(List 1, List 2, N).

Sum of Sequence —— (smSq)

This command obtains a function that expresses the sum up to the

n

th term of a

sequence of numbers.

• The function is a linear algebra expression.
