![]() That just means that you need to make an expression that helps you find the next number in the sequence. We often say that we can find an expression f n for the nth number in a sequence. If you know that the sequence is arithmetic, you can follow this recipe to make an expression for it. It does follow a pattern, as I’m sure you can tell, but it doesn’t increase by the same number every time. In the sequence 1, 3, 6, 1 0, 1 5, 2 1, … ,Įach term does not increase by the same number, meaning it’s not arithmetic. Is arithmetic, as each term increases by 3. When you figure out what’s going on, you will be able to find an expression for any term in an arithmetic sequence. Sequences that increase by a constant number has their own cool name, which is arithmetic sequences. Those that don’t increase by a constant number. Those that increase by a constant number, 2. Sequences can be divided into two main types: 1. They can be written as a list of number separated by commas, or they can be drawn as figures. On the top (numerator), the next term is 1 more than the previous one, and the bottom (denominator), the next term is the previous term multiplied by 2.A sequence is a set of numbers in a specific order. For example, try to find the next few terms in the following sequences:Įvery term is cubed. You may have heard the term inductive reasoning, which is reasoning based on patterns, say from a sequence (as opposed to deductive reasoning, which is reasoning from rules or definitions). Sequences are the list of these items, separated by commas, and series are the sum of the terms of a sequence (if that sum makes sense it wouldn’t make sense for months of the year). Each of these numbers or expressions are called a term or an elements of the sequence. Sequences are basically just numbers or expressions in a row that make up some sort of a pattern for example, January, February, March, …, December is a sequence that represents the months of a year.
