The common difference is



EXPLANATION

We want to find the common difference of the arithmetic sequence,



The common difference is the constant difference between any two consecutive terms.

Thus,



For instance the first and second term of the sequence has the difference,



Or the third and the second term has the difference,


Since this is an arithmetic sequence the difference is the same for any two consecutive terms.
