Is the difference between consecutive terms constant?

Is It Arithmetic? Yes
Sequence: $4, 6, 8, 10$ Explanation: See solution.

Practice makes perfect

Let's count the number of smileys in each group. We will also determine how many smileys are added from one group to the other.

The arithmetic sequence 4, 6, 8, 10 with the common difference marked between each term

For an arithmetic sequence, the difference between consecutive terms is constant. Here, each term is $2$ greater than the previous one. Therefore, the sequence is arithmetic.
