Final answer:
The rule for the given pattern is to divide each number by 2 to obtain the next number in the sequence.
Step-by-step explanation:
The rule for the pattern 300, 150, 75, 37.5, 18.75 is that each number is half of the previous number.
The pattern follows a rule of dividing each term by 2 to obtain the next term. The first term, 300, divided by 2 gives 150, which is the second term. Continuing this pattern, we divide each subsequent term by 2 to find the next term.
To find the next number in the sequence, simply divide the last number by 2. For example, starting with the first number, 300, and dividing it by 2, you get the second number, 150. If you continue this process, dividing each subsequent number by 2, you will get the next number in the pattern. This operation is repeated to continue the sequence indefinitely. So the next number after 18.75 would be 18.75 divided by 2, which is 9.375.
