What would you say is the next entry in this series?

2525, 3535, 4545, 5555, 6565, ...

It looks like the next entry SHOULD be 7575, doesn't it? Just add 1010, right?

Well, the next entry WOULD be 7575 - if this were a mathematical series. But that wouldn't be much of a challenge, would it?

The next entry is actually less than 7575, because this is not about arithmetic, and the pattern changes after 6565.

Can you figure out what the next entry is?


I hope it doesn't take you YEARS to find it. Sing out when you do!
