The sequence is decreasing by one more than the previous time.

For example...

The difference between 46 and 45 is

The difference between 45 and 43 is

The difference between 43 and 40 is

The difference between 40 and 36 is

This means that the next number in the sequence is 36 - 5, which is

The sequence will then continue 25, 18, 10, 1...

For example...

The difference between 46 and 45 is

**1**The difference between 45 and 43 is

**2**(which is one more than last time)The difference between 43 and 40 is

**3**(which is one more than last time)The difference between 40 and 36 is

**4**(which is one more than last time)This means that the next number in the sequence is 36 - 5, which is

**31.**The sequence will then continue 25, 18, 10, 1...
