that both the numerator and denominator approach 2/(1+sqrt(5)) = 1/phi ~= .6180339887498948, so that the fraction approaches 1. (wrong; see below)
(Sorry; misunderstood function  the signs don't alternate as assumed below)
All the 2's in the function predominate over the lone 3, when 3 is used.
DEFDBL AZ
x = 3
f = SQR(x)
DO
f = SQR(2 + f)
f = SQR(2  f)
PRINT f
LOOP
