2.) Arithmetic. common difference: 4

3.) Not arithmetic.

Answer 2

Answer:

Step-by-step explanation:

The first two have a common difference of 4

2 6 10

To get from 2 to 6 you need to add 4 to the 2.

-7 -3 1

Add 4 to -3 and you get 1. This works.

The last one seems to be playing hop scotch all over the place (hop scotch is not a technical term. It is just by way of saying it's not arithmetic).
