Identify a patterning the following 12 17 22

In this question, we're trying to find the pattern of the numbers: 12, 17, and 22.

To find the pattern, we must find how much it's changing by.

We see that it's increasing every time, so the change would be positive.

If you subtract 17 by 22, you would get 5.

If you subtract 22 by 17, you would still get 5.

12 + 5 = 17

17 + 5 = 22

This means that the pattern is 5.
