When you think about it, there are 30 /consecutive/ twenties in 600. There are only five "twenties" however. 20, 120, 220, 320, 420, and 520.
Or look at it this way: you have 1-20. That's one. Then you have 2-21. That's another twenty. Two. Then there's 3-22. Three. Etc. on up to 581-600. So, there are 581 twenties in 600. Unless you count all the number ranges possible, including all the rational and Irrational Numbers that are precisely twenty apart. Then there are an infinite number of :"twenties."
Example: Square root of 13 to (square root of 13) + 20.
There are approximately 15 twenties in 300. 400 will have 20 twenties.
