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).
