-5,3,-2,1,-1,0,__,__?
360,180,120,90,__,__?
thanks
what I see ...
1st sequence, note the differences:
8, 5, 3, 2, 1 ... looks like a Fibonacci sequence backwards with alternating signs.
2nd sequence:
(1)360, (1/2)360, (1/3)360, (1/4)360, ...
these are just sequences the author came up with so that you could play the "guess what I had in mind" game ... imho.
look at the first "sequence" backwards ...
0, -1, 1 , -2, 3 , -5
ignore the signs for a moment ...
0, 1, 1, 2, 3, 5
except for the first two terms, each subsequent term is the sum of the two prior terms, then the signs were made to alternate.
to tell you the truth, I sort of believe the sequence "pivots" at 0 and just runs in the same manner with alternating signs
-5,3,-2,1,-1,0, 1, -1, 2, -3, 5 ...
as I stated earlier, this is not a mathematical sequence ... it's a "guess what I did" exercise.
