Answer:
Arithmetic sequence
Explanation:
In an arithmetic sequence, the next term on the sequence is obtained by adding a certain value to the first term. This term that is added is uniform throughout the sequence. Once this term is added to the preceding term, the next term of the sequence is obtained. This term that is thus added is known as the common difference of the arithmetic sequence.
So the arithmetic sequence obtained by adding 4 starting from 2 is; 2, 6, 10, 14 .........
