A sequence is a list of numbers, geometric shapes or other objects, that follow a specific pattern. The individual items in the sequence are called terms, and represented by variables like x n. A recursive formula for a sequence tells you the value of the nth term as a function of its previous terms the first term.

This pre-algebra video tutorial explains how to find the next term in a number series. It provides plenty of examples of finding patterns in arithmetic and geometric sequences. This lesson ...

Number sequence (i) is a list of numbers without order or pattern. You cannot tell what number comes after 5. Number sequence (ii) has a pattern. Do you observe that each number is obtained by adding 3 to the preceding number (i.e. the number just before it)? In this section, we will only study number sequences with patterns . Some other ...

Sequences - Finding a Rule. To find a missing number in a Sequence, first we must have a Rule. Sequence. A Sequence is a set of things (usually numbers) that are in order.. Each number in the sequence is called a term (or sometimes "element" or "member"), read Sequences and Series for a more in-depth discussion.. Finding Missing Numbers

3.2 Describing sequences (EMAY). A sequence is an ordered list of items, usually numbers. Each item which makes up a sequence is called a “term”. Sequences can have interesting patterns.

Can you detect a pattern in this sequence? Continue. The number of rabbits in a particular month is the sum of the two previous numbers twice the previous number. In other words, you have to add the previous two terms in the sequence, to get the next one. The sequence starts with two 1s, and the recursive formula is. x n = x n − 1 + x n − 2

Notice that in option A, to get to the next number, just add 100 every time. We call this pattern an arithmetic sequence. To learn more about this type of sequence, go to arithmetic sequence. In option B, to get to the next number, just multiply by 3 every time. We call this pattern a geometric sequence.

Common Number Patterns Numbers can have interesting patterns. Here we list the most common patterns and how they are made. Arithmetic Sequences. An Arithmetic Sequence is made by adding the same value each time.
