Type the missing number in this sequence: 45, 39, _____, 27, 21, 15, 9

Identify Pattern: We need to identify the pattern in the sequence. Let's look at the difference between the consecutive numbers that are given. 45 - 39 = 6 So, the difference here is 6.Check Consistency: Now let's check if the same difference applies to the other given numbers in the sequence. 27 - 21 = 6 21 - 15 = 6 15 - 9 = 6 It seems that the pattern is consistent, and the sequence decreases by 6 each time.Find Missing Number: To find the missing number, we subtract 6 from 39, which is the number immediately before the missing number in the sequence. 39 - 6 = 33 So, the missing number should be 33.Verify Solution: Let's quickly verify that adding 6 to the missing number gives us the next number in the sequence. 33 + 6 = 39 This confirms that our pattern is correct and the missing number is indeed 33.

Identify Pattern: We need to identify the pattern in the sequence. Let's look at the difference between the consecutive numbers that are given. $\newline$ $45 - 39 = 6$ $\newline$ So, the difference here is $6$ .
Check Consistency: Now let's check if the same difference applies to the other given numbers in the sequence. $\newline$ $27 - 21 = 6$ $\newline$ $21 - 15 = 6$ $\newline$ $15 - 9 = 6$ $\newline$ It seems that the pattern is consistent, and the sequence decreases by $6$ each time.
Find Missing Number: To find the missing number, we subtract $6$ from $39$ , which is the number immediately before the missing number in the sequence. $\newline$ $39 - 6 = 33$ $\newline$ So, the missing number should be $33$ .
Verify Solution: Let's quickly verify that adding $6$ to the missing number gives us the next number in the sequence. $\newline$ $33 + 6 = 39$ $\newline$ This confirms that our pattern is correct and the missing number is indeed $33$ .
