find the missing number in each sequence... 30,_____,19, 13 1/2
This is horrible don't use it does not give you the answer
To find the missing number in the given sequence, we need to look for a pattern or relationship between the consecutive numbers.
Let's analyze the numbers given:
- 30
- _____ (missing number)
- 19
- 13 1/2
From 30 to 19, we can observe that the numbers are decreasing. Now, let's look at the jump between 19 and 13 1/2. It appears to be a decreasing sequence as well.
To continue the pattern, we need to determine the difference between each pair of consecutive numbers. The difference between 30 and 19 is 11 and the difference between 19 and 13 1/2 is 5 1/2.
So, we can assume that the pattern involves subtracting a decreasing value each time. To find the missing number, we subtract the next value in the sequence, which is 5 1/2, from 13 1/2.
13 1/2 - 5 1/2 = 8
Hence, the missing number in the sequence 30, _____, 19, 13 1/2 is 8.
30-19 = 11
so split the difference. It will be the same as 19 - 13 1/2
