The given sequence is -12, 60, -300, 1500. To find the pattern or rule in this sequence, we need to analyze the relationship between the numbers.

Looking at the sequence, we can observe that each number is multiplied by -5 in order to get the next number. Let's see this:

-12 * (-5) = 60
60 * (-5) = -300
-300 * (-5) = 1500

So, the rule for this sequence is to multiply each number by -5 to obtain the next number.

Therefore, the next number in the sequence can be found by taking the last number and multiplying it by -5:

1500 * (-5) = -7500

Hence, the next number in the sequence is -7500.
