The common difference is the difference between any two consecutive terms in an arithmetic sequence.
In this case, we can see that the fifth term is obtained by adding 8 to 3 times the difference between 5 and 1. So the difference between the fifth term and the fourth term is 3.
Therefore, the common difference is 3.
Given the explicit formula : a5=8+ (5-1) 3
