I was solving it in my code editor first, didn't try it here
I had only one step missing and I couldn't figure it out because every time I try to debugg I get an infinite loop

Kata description says:

We will call the series seeded by a value of 1 the "base series"

what is the "base series"?

Did you finish it?

Sounds like Python. Also sounds like your function does not return a value.

'None should equal 283' - what it means?

Does it mean that function should be able to process something else except numbers?

Tests are not supposed to time out. That wouldn't make sense.

please add to instructions that large inputs cause timeout, I spent the last two hours banging my head against the wall trying to figure out what's wrong with my code
