Check the following series and predict the next 3-4 numbers .. Also, if you can figure it out, what is the relation between these numbers ?? what is the formula?

81
45.5
81

if you subtarct 35.5 from 81 it gives 45.5 n when you add it , it gives 81 again. When subtract 35.5 from 45.5 it gives 10 now add it.... next number should be 45.5

i think its a platonic one.
if it was a simple harmonic or geometric type, it would not have been posted on echarcha.

The series goes like this...

81
45.5
81
45.5
10
10
-4.2
-18.4
-32.6
-46.8


Don't ask me the formula, tell me how these numbers are derived. I couldn't work it out.

Okay after that ten ...subtarct 14.2 from 10 it gives -4.2 right then add -4.2 n -14.2 it gives you -18.4 , then add -18.4 to -14.2 it gives you -32.6 keep adding -14.2 to the previous answer.
