Arithmetic is a branch of mathematics that deals with the properties and manipulation of numbers. It involves performing mathematical operations such as addition, subtraction, multiplication, and division on numbers to obtain results. In arithmetic, you can use symbols and equations to represent numbers and the operations you perform on them.
Number sequences; are a set of numbers that follow a certain pattern or rule. Each number in the sequence is related to the previous number in some sort of way. Number sequences can be finite, meaning that they have a specific number of terms, or infinite, meaning that they continue indefinitely.
A simple arethmetic sequence could be:
1, 3, 5, 7, 9, 11, …
This sequence follows the pattern of adding 2 to each previous number to get the next number in the sequence. In this case, the common difference between each term is 2.
Here is another example; a geometric sequence:
2, 4, 8, 16, 32, 64, …
In this sequence, each term is found by multiplying the previous term by 2. The common ratio between each term is 2.
Knowing what & how an arithmetic/number sequence is & will help you when it comes to math; taking an aptitude test to get into an apprenticeship. And further down the road in the trades math is used!
