AI explanation

The series follows a pattern of alternating multiplication and addition. The first term 6 is multiplied by 2 to give 10 (due to potential typo in standard exams), but correctly, 6 multiplied by 1 plus 4 equals 10. Then, 10 multiplied by 2 plus 7 equals 27, 27 multiplied by 1 plus 25 equals 52, and 52 multiplied by 3 minus 3 equals 153. The alternating multiplier and addend pattern shows 6 x 1 + 4 = 10, 10 x 3 - 3 = 27, 27 x 2 - 2 = 52, and 52 x 3 - 3 = 153, so the missing term is 153 x 2 - 2, which equals 304.
