At each step the number being subtracted is reduced by 9 298 - 89 = 209 209 - 80 = 129 129 - 71 = 58 58 - 62 = -4 -4 - 53 = -57..........which is the next number.
-57 298 - 89 = 209 209 - 80 = 129 129 - 71 = 58 58 - 62 = -4 -4 - 53 = -57 notice every number is subtracted by 9 less than the previous number's subtrator

Oh, dude, you're throwing some numbers at me like we're playing math dodgeball. So, like, to find the pattern, it's like taking a stroll through a number garden. If you squint real hard, you'll see that we're just subtracting decreasing numbers each time. So, the next number is probably going to be like -4 minus something, but who's really keeping track, right?
The sequence is formed by subtracting 89 at the first step and then reducing this figure by 9 at each successive step. 298 - 89 = 209 209 - 80 = 129 129 - 71 = 58 58 - 62 = -4 -4 - 53 = -57........this is the next number in the series.

-57. You are taking away 9 less each time.
