• f(1) = 8
  • f(2) = 5.25
  • f(3) = 3.5
  • f(4) ≈ 2.4
  • f(5) ≈ 1.67

And going the other way f(n-1) = (11/7 f(n) - 1/4) we get laserdiscs?

  • f(1) = 8
  • f(0) ≈ 12.32

    Interesting, is this a coincidence or is there a logic/reason it works out that way?

        Ah ok. I was more wondering if it related to the bit density on magnetic tape or speed of the stepper motor available for a reasonable price at the time or something like that.

          Because that’s the sequence I wanted the result to be - 8 ➡️ 5.25 ➡️ 3.5

          I knew they wouldn’t multiply or divide exactly so there’d need to be a second term in there.

          a turned out to be 7/11, and b turned out to be 1/4.
