Sequence Command
From GeoGebra Manual
- Sequence[ <Expression>, <Variable i>, <Number a>, <Number b>]
- Yields a list of objects created using the given expression and the index i that ranges from number a to number b.
- Example:
L = Sequence[(2, i), i, 1, 5]creates a list of points whose y-coordinates range from 1 to 5:L = {(2, 1), (2, 2), (2, 3), (2, 4), (2, 5)}.
- Sequence[ <Expression>, <Variable i>, <Number a>, <Number b>, <Increment>]
- Yields a list of objects created using the given expression and the index i that ranges from number a to number b with given increment.
- Example:
L = Sequence[(2, i), i, 1, 3, 0.5]creates a list of points whose y-coordinates range from 1 to 3 with an increment of 0.5:L = {(2, 1), (2, 1.5), (2, 2), (2, 2.5), (2, 3)}.
- Note: Since the parameters a and b are dynamic you could use slider variables in both cases above as well.
- Sequence[ <Number b> ]
- Creates list of numbers 1 to b, e.g. {1, 2, ..., b}.
- Example:
L = 2^Sequence[4]creates list {2, 4, 8, 16}.
- Note: See Lists for more information on list operations.
CAS Syntax
- Sequence[ <Expression>, <Variable i>, <Number a>, <Number b> ]
- Yields a list of objects created using the given expression and the index i that ranges from number a to number b.
- Example:
Sequence[x^i, i, 1, 10]generates the sequence {x, x², x³, x⁴, x⁵, x⁶, x⁷, x⁸, x⁹, x¹⁰}.
- Sequence[ <Expression>, <Variable i>, <Number a>, <Number b>, <Increment>]
- Yields a list of objects created using the given expression and the index i that ranges from number a to number b with given increment.
- Example:
Sequence[x^i, i, 1, 10, 2]generates the sequence {x, x³, x⁵, x⁷, x⁹}.
- Sequence[ <Number b> ]
- Creates list of numbers 1 to b, e.g. {1, 2, ..., b}.
- Example:
Sequence[5]generates the sequence {1, 2, 3, 4, 5}.
