For an arithmetic sequence, the common difference is the difference of any two consecutive terms. Expressed mathematically, the common difference is

`s_(n+1)-s_n` where  `n` is any natural number. In this arithmetic sequence, the common difference is

`1.5-0.7=0.8.` You can check that you get the same thing no matter which consecutive terms you use. That is,

`3.1-2.3=0.8,` and `2.3-1.5=0.8` as well.

The common difference is 0.8.
