Study the data below and 15,16,14,7?

It appears that the data is a sequence of numbers. The pattern in the sequence is not immediately clear, as there is a jump from 14 to 7. However, if we look at the differences between each number in the sequence, we can see that the differences are as follows:

16 - 15 = 1
14 - 16 = -2
7 - 14 = -7

Based on this pattern, the next number in the sequence would be 7 - 7 = 0.
