a silly puzzle: do you know what this is?

Can you tell what this series of numbers represents?

98-0
99-1
00-2
01-3
02-4
03-5-k
04-6-1
05-7-2
06-8-3
07-9-4
08-10-5
09-11-6
10-12-7
11-13-8
12-14-9


I was just writing it out (again. That's a bit of a hint.) & it struck me that it looks like a weird code & I wondered how many of you would recognize it.

Obviously you can see the #'s increasing by 1 but what do they mean? Tell me in the comments if you know :)

I have some strawberries in pots on the railings (on the railings because a. Bear pees on things & b. Daisy eats berries & tomatoes right off the plants). Look who came to help himself (herself?) And the dogs slept through it all.
