#### Answer

A sequence in which each term after the first differs from the preceding term by a constant amount is called an arithmetic sequence. The difference between consecutive terms is called the common difference of the sequence.

#### Work Step by Step

Arithmetic sequence: It is a sequence where after the first term the difference between every term and its preceding term is a constant. The difference between the consecutive terms is called the common difference of the sequence. Common difference: An arithmetic sequence is a group of numbers presented in a specific pattern. A constant number is added to each number of the sequence to find the next number of the series. The number which is added should be the same for each term of the sequence. Thus, the number which is added to the previous number to find the next number is called the common difference.
