Tell whether the sequence is arithmetic. If it is, what is the common difference?
2, 7, 13, 20...
(1 point)
A) yes; 5
B) yes; 6
C) yes; 2
D) no
The sequence is arithmetic because there is a consistent pattern in the differences between terms.
To check the difference between terms, we subtract each term from the next term:
7 - 2 = 5
13 - 7 = 6
20 - 13 = 7
The differences are not the same, so the sequence is not arithmetic.
Therefore, the answer is D) no.
