Here's my logic (Not homework help, just some random thing lol)

[Flo-Flo Chique]

This is how my logic works:

I predicted a time frame in which Microsoft might release Windows 16. It should be around 2036. I basically did this (I will make it look mathematical)

average release time frame x Windows version (number) = X
X - Current Year = Y
Add 20 before Y = release date

Therefore,

3x16=48
48-12=36
20 before 36 = 2036
2036 = Possible release time frame

Windows 25:

3x25=75
75-12=63
20 before 63 = year 2063
2063 = Possible release time frame

Not that these random calculations are just speculations and are not accurate lol. This won't work for a version of Windows that has already been released. Or maybe...

Start from 2005, predicting Windows 7:

3x7=21
21-5-5=11
20 before 11 = 2011
2011 = Possible release date

Pretty close, actually :D
