Hi, hope you all are doing well. I need help building a formula, if someone can be so kind to help me I would be very grateful.

Per the image, I have a data series on column "A", on column "B" I need a formula that checks how many "x" it takes, until there is a inverse 2x change of "x".


So, for example, if "x" = 0,10 ; 2x = 0,20 ;

From our inputs, the lowest number is "1" (A1) and the highest is "2" (A7) , on cell (A10) we have a 2x change of "x" (2-0,20 = 1,80) ; So it took 10x to reach there. (2-1 = 1) / 0,10 = 10

So "10" should be displayed on (B10), until there is a new 2x change of "x" again. Example two: (2,5-1,8 = 0.7) / 0,10 = 7 on cell (B14)

Thank you for the help and time

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.
