find the next two numbers in the pattern:

-12, 60, -300, 1500

clearly there is no constant difference.

Check for constant ratio

(-12)(-5) = 60
(60)(-5) = -300
...
we have a winner. SO, what is

1500 * -5 ?

-12,60,-300,1500

To find the next numbers in the pattern, let's look for a common relationship or pattern between the given numbers. In this case, the pattern seems to be multiplying each number by -5.

Let's break it down step-by-step:

First number: -12
-12 * -5 = 60

Second number: 60
60 * -5 = -300

Third number: -300
-300 * -5 = 1500

So, the pattern is that each number is obtained by multiplying the previous number by -5.

Now, let's continue the pattern:

Fourth number: 1500
1500 * -5 = -7500

Fifth number: -7500
-7500 * -5 = 37500

Therefore, the next two numbers in the pattern are -7500 and 37500.
