The given arithmetic sequence is -7, -2, 3, 8, .

The d value or the common difference is the difference between any two consecutive terms in an arithmetic progression.


To find the common difference, subtract a pair of terms. It doesn't matter which pair is picked, as long as they are right next to each other:




The difference is always 5.

So, d=5.
