Understanding Sequences and Ordered Pairs

The video tutorial explains two sequences of numbers, Sequence x and Sequence y, with their starting numbers and rules. Sequence x starts at 1 and increments by 1, while Sequence y starts at 5 and increments by 5. The tutorial demonstrates how to fill in a table with the first three terms of each sequence and plot them as ordered pairs on a graph. It highlights the relationship between the sequences, showing that terms in Sequence y are five times the terms in Sequence x.
