Type the missing number in this sequence: 19, _____, 17, 16, 15, 14

Identify Pattern: We need to identify the pattern in the sequence to find the missing number. Let's look at the numbers we have: 19, 17, 16, 15, 14. It seems that the sequence is decreasing. To confirm the pattern, we calculate the difference between each pair of consecutive numbers.Calculate Differences: The difference between 17 and 16 is 1, between 16 and 15 is also 1, and between 15 and 14 is again 1. This suggests that the sequence is decreasing by 1 each time. Now let's check the difference between the first two numbers we have: 19 and 17.Analyze First Two Numbers: The difference between 19 and 17 is 2. This indicates that the sequence decreases by 2 to get from 19 to the missing number, and then by 1 for each subsequent number. Therefore, the missing number should be 1 less than 19, which is 18.

Identify Pattern: We need to identify the pattern in the sequence to find the missing number. Let's look at the numbers we have: $19$ , $17$ , $16$ , $15$ , $14$ . It seems that the sequence is decreasing. To confirm the pattern, we calculate the difference between each pair of consecutive numbers.
Calculate Differences: The difference between $17$ and $16$ is $1$ , between $16$ and $15$ is also $1$ , and between $15$ and $14$ is again $1$ . This suggests that the sequence is decreasing by $1$ each time. Now let's check the difference between the first two numbers we have: $16$ $0$ and $17$ .
Analyze First Two Numbers: The difference between $19$ and $17$ is $2$ . This indicates that the sequence decreases by $2$ to get from $19$ to the missing number, and then by $1$ for each subsequent number. Therefore, the missing number should be $1$ less than $19$ , which is $18$ .
