Answer:

This is a very nice question and very easy because it extends to infinity.

If you assume the whole thing as x,

the denominator becomes x too(infinity here)

so we get

x = 20 + 1/x

=> x^2 = 20x + 1 (multiplying by x)

=> x^2 - 20x -1 = 0

=> x = (20+√(400+4))/2 and (20-√(400+4))/2

=> x = 20.05 and -0.05 approx
