Something else I noticed is the number used, none of the examples has a zero in it.

A Grade 7 Math Guide to Sequences and Series
In this lesson, we will learn about sequences.
A sequence is a list of numbers that usually possess a certain pattern.
The numbers in the sequence are called terms.
We will learn two important types of sequences.
One type of sequence is called an arithmetic sequence.
An arithmetic sequence is a sequence that has a common difference between two terms.
For example, the sequence 1, 3, 5, 7, 9 has a common difference of 2 between two consecutive terms.
Another type of sequence is called a geometric sequence.
A geometric sequence is a sequence that has a common ratio between two terms.
For example, the sequence 2, 1/2, 1/8, 1/32 has a common ratio of 1/4 between two consecutive terms.
