Tell whether the sequence is arithmetic. If it is, what is the common difference?

Question

3,7,12,18,
(1 point)
• Yes, 4
• Yes, 5
• Not arithmetic
• Yes, 3

Answer 1

Not arithmetic

Answer 2

Are you sure

Answer 3

Yes, I am sure. The sequence 3, 7, 12, 18 does not have a common difference. To determine if a sequence is arithmetic, we need to check if the difference between each consecutive term is constant. In this case, the differences are 7-3 = 4, 12-7 = 5, and 18-12 = 6, which are not the same. Therefore, the sequence is not arithmetic.
