AI explanation

The correct pattern alternates by adding multiples of 7 and subtracting multiples of 5. The pattern starts from 420, adds 7 to get 427, subtracts 1 to get 426, adds 14 to get 440, subtracts 8 to get 432, adds 21 to get 453, and subtracts 15 to get 438. The number 429 does not fit this logic and is the wrong term.
