The sequence is arithmetic if the difference between every two consecutive terms is always the same.
An arithmetic sequence is an ordered set of numbers such that the difference between any two successive members of the set is a constant.
An arithmetic sequence is an ordered set of numbers such that the difference between any two successive members of the set is a constant.
A sequence of numbers in which the difference between any two consecutive terms is the same is called an arithmetic sequence or arithmetic progression. For example, in the sequence 2, 5, 8, 11, the common difference is 3. This consistent difference allows for predictable patterns and calculations within the sequence.
To check whether it is an arithmetic sequence, verify whether the difference between two consecutive numbers is always the same.To check whether it is a geometric sequence, verify whether the ratio between two consecutive numbers is always the same.
