Explanation

The pattern is: 12*3 + 2 = 38; 38*4 - 2 = 150; 150*5 + 2 = 752; 752*6 - 2 = 4510. The multiplier increases by 1 and the constant alternates between +2 and -2.

AI explanation

The logic in this series is multiplying the previous term by a specific number and then adding an even number that doubles each time. Multiplying 12 by 3 and adding 2 gives 38, multiplying 38 by 3 and adding 36 gives 150, and applying the same rule means multiplying 150 by 3 and adding 302 gives the missing number 752. We can verify this because multiplying 752 by 3 and adding 2254 successfully produces the final term 4510, though the addition component is a bit odd, this is the intended path.
