@DavidK Did you ever expand on the reverse sequence/ backward sequence from this thread? Doubling sequences of the cyclic decimal parts of the fraction numbers

"I'll give some thought to what can be said about that in not too many words." The right to left order of repetends is something I have been researching. Thanks.

  • right to left? but that's finite – Saketh Malyala Apr 28 '19 at 19:32
  • For example 1/95 can be expressed as "1/95 = 1/(100 - 5) = (1/100)/(1 - 5/100) =(1/100)[1 + 5/100 + (5/100)^2 + (5/100)^3 + ...] =01 + .0005 + .000025 + .00000125 + ..." showing the geometric series from left to right. The same repetend can be seen from right to left when observing powers of two: "\sum_{k=0}^n {20^k} = {{20^{k+1} -1} \over {19}}" – Michele Mikulskis Apr 28 '19 at 19:37
