Using TI-83/84 for Summation

This video tutorial demonstrates how to use the TI-83 or TI-84 graphing calculator to determine sequences and series. It covers generating sequences using a formula, finding the sum of a series, and summing a list of terms. The tutorial provides step-by-step instructions for each process, ensuring users can verify their manual calculations with the calculator.

What is the first step to access the sequence function on the TI-83/84 calculator?

• Press 2nd, then LIST, and right arrow to OPS

• Press MODE, then select SEQ

• Press GRAPH, then select SEQ

• Press ALPHA, then MATH

When inputting a formula for a sequence, which variable is used instead of 'N'?

• Y

• Z

• X

• A
