prime numbers – correct description of a sequence with a specified fractal property

I have a sequence A with the fractal model as the innermost values ​​x, where length (x) = length (A) / 2, has the sum (x) = the sum (A) / 2. C & # 39, is also a fractal pattern, so that for the sequence x with the fractal pattern, the most internal values ​​y, where length (y) = length (x) / 2, has the sum (y) = the sum ( x) / 2. This continues as long as the innermost length is divisible by 2. Example:

A = 31.18,37.24,27,46,33,36,23, -6, -3,16,19,38,41,12, -1,2, -11,8,11, -2 , 17.4
x = 33.36,23, -6, -3,16,19,38,41,12, -1,2
y = -6, -3,16,19,38,41

A (length) = 24
A (sum) = 420
x (length) = 12
x (sum) = 210
y (length) = 6
y (sum) = 105

What is a concise way to describe this property? Thank you!
