What is the rule for this sequence?
72 , 63 , 54 , 45 , 36
Each number in the sequence is 10 less than the previous number.
Each number in the sequence is 9 less than the previous number.
The sequence decreases by multiples of 9. First by 9, then 18, then 27, then 36.
The sequence decreases by multiples of 10. First by 10, then 20, then 30, then 40.

Each number in the sequence is 9 less than the previous number.
The rule for this sequence is that each number in the sequence is 9 less than the previous number. To determine this, you can observe the pattern of the numbers: 72, 63, 54, 45, 36.
To find the rule, you can subtract each number from its preceding number. In this case, 72 - 63 = 9, 63 - 54 = 9, 54 - 45 = 9, and 45 - 36 = 9. Since each subtraction results in 9, we can conclude that each number in the sequence is 9 less than the previous number.
Therefore, the correct answer is: Each number in the sequence is 9 less than the previous number.
