Sequences are a topic of study in calculus. The TI-83 and the TI-84 will list the terms in a defined sequence.

Example: Find the first 6 terms of the sequence . Note in window two below how the sequence is entered. The variable X is used instead of an n. The name of the variable is not important as long as you use the same one. The proper way to enter a sequence is: seq(definition, variable, starting value, ending value, increment). For this example we have: seq(2X-1,X,1,6,1) that will start the sequence at 1 and give 6 values in increments of 1.

Access sequence.
Enter the sequence.
