-57
The first two numbers in the series has a difference of 89. The next two numbers (209, 129) has a difference of 80. The next two (129,58) has a difference of 71. As you can see the differences change by 9, so the next two numbers in the series (58, -4) has a difference of 62. Following this pattern, the next two numbers in the series will have a difference of 53. So the next number in this series will be (-4-53 = -57).
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.
The next number in the series 1 2 4 8 10 20 22 is
it is 31818 - 8 = 1010 - 4 = 66 - 2 = 44 - 1 = 3

11 comes next.
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.
The next number in the series 1 2 4 8 10 20 22 is
it is 31818 - 8 = 1010 - 4 = 66 - 2 = 44 - 1 = 3
10
The next number in the series 4, 12, 6, 12, 36, 18, 36
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 next number in the series 4-12-6-12-36-18-36.. is 108.

The pattern in this series is not immediately apparent, as the numbers seem to be jumping around. However, upon closer inspection, we can see that the series alternates between adding and subtracting a specific number. The next number in the series should be 10, as we continue the pattern of adding and subtracting 1, 3, -3, 5, -5, 7, and so on.
