Question Number 61625 by Sharath Kumar last updated on 05/Jun/19

1+(1/(1+(1/(1+(1/(1+(1/(1+(1/(1+...))))))))))=

$$\mathrm{1}+\frac{\mathrm{1}}{\mathrm{1}+\frac{\mathrm{1}}{\mathrm{1}+\frac{\mathrm{1}}{\mathrm{1}+\frac{\mathrm{1}}{\mathrm{1}+\frac{\mathrm{1}}{\mathrm{1}+...}}}}}= \\ $$

x=1+(1/x) ∧ x>1 ⇒ x=(1/2)+((√5)/2)

$${x}=\mathrm{1}+\frac{\mathrm{1}}{{x}}\:\wedge\:{x}>\mathrm{1}\:\Rightarrow\:{x}=\frac{\mathrm{1}}{\mathrm{2}}+\frac{\sqrt{\mathrm{5}}}{\mathrm{2}} \\ $$

(((√5)+1)/2)=1.61803398.....      isn′t it Golden Ratio.

$$\frac{\sqrt{\mathrm{5}}+\mathrm{1}}{\mathrm{2}}=\mathrm{1}.\mathrm{61803398}.....\:\:\:\:\:\:{isn}'{t}\:{it}\:{Golden}\:{Ratio}. \\ $$
