I apologize for the mistake in my previous response. You are correct. The sequence 8, 15, 22, 30 is not arithmetic since the common difference between terms is not constant. The first two terms are added by 7, but between the third and fourth terms, the addition changes to 8. Thank you for bringing this to my attention.
