Ok, so I really don't remember a lot about sequences except for that they are related in some sort of equation. I'm not guaranteeing this is right but heres my best guess.
88511/16351= 5.41....
I'm assuming that 20251 will have the same ratio with the number before it so the number that is 5.41... times bigger than 20251 is 109622. Thats my best guess. Sorry I couldn't help more.
