AI explanation

The underlying pattern of the series subtracts consecutive prime numbers from the previous term. The sequence of prime numbers starting from 7 is 7, 11, 13, 17, 19, 23, and 29. Following this rule, 351 - 7 = 344, 344 - 11 = 323, and 323 - 13 = 310. The number 298 is incorrect because it should be 310.
