49 (it is an arithmetic series that adds 5 then 7 then 9 then 11 then 13)

This is the series of square numbers, (16= 4*4). The next number is 5*5=25.

They are: 33 29 25 21 17 13 9 a reduction of 4 each time

The next number in the series 1 2 4 8 10 20 22 is

3 The series is obtained by subtracting a number that reduces by 1 at each stage 18 - 5 = 13 13 - 4 = 9 9 - 3 = 6 6 - 2 = 4 4 - 1 = 3

The difference between one number and the next in the sequence is decreasing by 9 each time. Therefore, the difference between -4 and the next number will be equal to 62 - 9 = 53. The next number is therefore equal to -4 - 53 = -57.

The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.

This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1

This is the series of square numbers, (16= 4*4). The next number is 5*5=25.

it is 31818 - 8 = 1010 - 4 = 66 - 2 = 44 - 1 = 3

The next number in the series 1 2 4 8 10 20 22 is

Since the numbers are going down be 5,4,3,2, the next number would be 3. It would be 3 because it would then go down by one.
