Explanation

The series is 197, 204, 211, 218, 225, 232, 239, 246, 253, 260. The difference is consistently 7. The term 245 is incorrect; it should be 246.

AI explanation

The series follows a simple addition pattern of 7 to each preceding term, starting from 197. Adding 7 repeatedly gives 204, 211, 218, 225, 232, 239, and 246. The term 245 is incorrect because adding 7 to 239 yields 246.
