What is the Sequencer Activity?

A Survey of Mathematics Related Topics: Pg. 6, Exercises 17-22

This activity allows the user to create sequences by varying the following values:
  • Starting Number: The first number in the sequence.
  • Multiplier: The number by which the preceding element of the sequence will be multiplied.
  • Add-on: The number that is added to the preceding number (after it has been multiplied by the multiplier) to obtain the next number in the sequence.

A given element of the sequence is obtained by multiplying the preceding number by the multiplier, and then adding the add-on. A graph of the resulting sequence and a list of the elements of the sequence are displayed in the applet.

For example, if our starting number is 1, our multiplier is 2 and our add-on is 3, we get the following numbers:

To obtain an arithmetic sequence enter "1" for the multiplier and to obtain a geometric sequence enter "0" for the add-on.
