### Hint

Notice the consecutive two-digit numbers, but over the comma.### Answer

A = 46B = 51

The numbers across the commas are divisible by eleven. For example, over the first comma is "33" which is 3x11. Over the eighth comma is 00, which is divisible by eleven.

## Comments

Interesting - I got it right, but I just noticed that the first digit of each number was the last digit of the previous number....

I solved this by knowing that the numbers next to each other were the same. Fun teaser nonetheless.

It was a fun teaser albeit pretty easy. No need for a hint.

Confusing at first but the hint gave it away. Even if it was easy I still wouldn't have got it though; I'm hopeless at sequences!

Good teaser. Well thought out and fun to work. Thanks for posting.

A more suitable answer would be: The first digit of any number is the same as the second digit before it. I don't think the eleven thingy makes any sense.
