This week, we started our Arithmetic Sequences. There are many diferent kinds of sequences, and these are classified by how the following/consecutive terms are determined.
Arithmetic Sequences:
These sequences are when the difference between each term is the same. For an example, here is one below.
5, 7, 9, 11, 13, 15. This kind of sequence has an arithmetic sequence with a common difference of 5. Tbis means that each term is increased by 2 to get the next one.
_______
Geometric Sequences:
These sequences are when each term is multiplied by a number that is not zero with a constant number. It is a list of numbers that are multiplied or divided by the same amount each time.
3, 9, 27, 81, 243. This kind of sequence has a geometric sequence with the constant number of 3. This means each term is multiplied by 3 to get the next one.
________
Other Sequences:
These sequences can include anything from cubed sequences (which the number of items/shapes in the term is cubed), there are also triangular sequences and squared sequences.
