How can you tell when a pattern shows counting on by ten?

when a pattern shows counting on by ten

For example, we assume a pattern counting by 10

10,20,30,40

If we count by 10 , then the difference between two terms is 10

Counting by 10 means common difference should be  10

In that example , 10,20,30,40

20 -10 = 10

30 - 20 = 10

40 - 10 = 10

We can see that the common difference is 10
