Why is it much harder to recite the alphabet in reverse than numbers when both follow a set order?

Both numbers and the alphabet follow a set order. "b" comes after "a" just as 2 comes after 1. But it is way more easier to recite numbers in reverse from any arbitrary number given but it is harder to recite the alphabet in reverse without practice.

Numbers follow a defined pattern that repeats after 10 items. You only have to remember 9 8 7 6.... Regardless of where you start, you know the next number down is one decrement from the previous, with a tens place to start. From fifty-seven you know the next is 56. Once you get to 50, all you need to know is that the next tens value down is forty and you know it’s 49. 

The alphabet doesn’t really work that way. What is the relationship between o and n? Or k and j? Or T and H? You have to memorize the entire string, rather than a simple pattern. It’s the same for when you first learned the alphabet. You memorized the order of letters. You just haven’t done that in reverse.
