nth term = success doesn't have to be about maths?

10, 20, 30, 40, 50, 60, 70, 80, 90, 20

70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 90?

I do this almost every time I am counting. I find it harder to count once I get passed 20, as the numbers get bigger. I always have to do a double take when counting in tens after ninety, as I always seem to say 20 instead of 100; maybe because it sounds like nineteen? I don't know. I also often say ninety or sixty after seventy-nine, even though it should obviously be eighty. It just doesn't make sense in my head.

Sequences of numbers can be challenging. Of course, as it is part of the syllabus, we have to do more complicated sequences in GCSE maths class and work out how much it's going up or down by etc. However when they go up by different numbers each time, seeing as I can't hold numbers in my head, it is very difficult to get anywhere at all. And when the nth term gets involved, well, I probably knew what that meant once, for about ten minutes.





...And the Fibonacci sequence sounds like some sort of arrangement of biscuits.
