To find a missing number in a Sequence, first we must have a RuleSequenceA 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....

Hence, by repeated application of the rule we can generate the sequence of numbers from any starting value. In the case of series, we are usually interested in their sum which can be achieved by the repeated operation of adding the next term in the series to the current value of the sum...
a = 3 (the first term) d = 5 (the "common difference") Using the Arithmetic Sequence rule: xn = a + d(n−1) = 3 + 5(n−1) = 3 + 5n − 5 = 5n − 2 So the 9th term is: x9 = 5×9 − 2 = 43 Is that right? Check for yourself!Arithmetic...
Generalization Strategies in Finding the nth Term Rule for Simple Quadratic SequencesIn this study, we identify ways in which a sample of 18 graduates with mathematics-related first degrees found the n th term for quadratic sequences from the first values of a sequence of data, presented on a...
Each object within a sequence is called a term. A typical sequence is written as: {eq}\lbrace a_{n} \rbrace {/eq} or {eq}\lbrace a_{n} \rbrace_{n=1}^{\infty} {/eq} Both of these notations are used to represent sequences. Here is an example of a sequence:...
The explicit rule to write the formula for any arithmetic sequence is this:an = a1 + d (n - 1)The an stands for the terms of the sequence where n refers to the location of the term. The d stands for the difference between all the successive pairs of your sequence. To use this ...
