Patterns and Sequences

A 'sequence' is an ordered set of numbers. Each number in the sequence is called a 'term'

Every term in the arithmetic sequence changes by the same amount

In most of the arithmetic sequences, the successive terms are formed by addition or subtraction of a certain value from the previous terms

A non arithmetic sequence generally involves the multiplication or the division operations and may even involve a combination of different operations

To identify the pattern in any series, look for a relationship among the first three terms. Check if this relationship applies to the fourth and the fifth terms and so on
