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
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 are also of interest in their own right and can be studied as patterns or puzzles, such as in the study of prime numbers. There are a number of ways to denote a sequence, some of which are more useful for specific types of sequences. One way to specify a sequence is to list the elements.

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 at Cool Math Games: Carefully plot your path to complete the sequence. Count up or down to hit all the targets.
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.
A number sequence is a list of numbers that are linked by a rule. If you work out the rule, you can work out the next numbers in the sequence. In this example, the difference between each number ...
This sequence of numbers of parents is the Fibonacci sequence. The number of ancestors at each level, F n, is the number of female ancestors, which is F n−1, plus the number of male ancestors, which is F n−2. This is under the unrealistic assumption that the ancestors at each level are otherwise unrelated.
Number; Number Sequences; Number Sequences . In the sequence 2, 4, 6, 8, 10... there is an obvious pattern. Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.
