Help pattern 0.88 , 0.84 , 0.82 what is the next two numbers that follow

Answer 1

you added -.04, then -.02
so, one pattern wold be to keep increasing the amount subtracted: .00, .02, .04, ...
or, keep halving the amount added -.01, -.005, ...

two or three points leave it pretty wide open for devising a pattern which fits.

Answer 2

88- 84 = 4 down 4
84 - 82 = 2 down 2
82 - 81 = 1 down 1
81 - 80.5= .5 down 1/2
so maybe 0.81 and 0.805 ?
