The Infinite Nested Radical: Unveiling the Mystery of $2=\sqrt{1+\sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+\sqrt{41+...}}}}}}$

The concept of nested radicals has been a subject of interest in mathematics for centuries. These expressions, which involve a series of nested square roots, can be used to represent a wide range of mathematical concepts, from algebraic equations to transcendental numbers. In this article, we will delve into the fascinating world of nested radicals and explore the specific expression $2=\sqrt{1+\sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+\sqrt{41+...}}}}}}$ . We will examine the properties of this expression, its connection to the golden ratio, and the implications of its existence in the realm of complex analysis.

The Golden Ratio and Nested Radicals

The golden ratio, denoted by the Greek letter phi ( $\phi$ ), is an irrational number that has been observed in various aspects of mathematics, art, and nature. It is approximately equal to 1.61803398875 and is often represented by the equation $\phi = \frac{1+\sqrt{5}}{2}$ . The golden ratio has unique properties that make it a fundamental element in mathematics, and its connection to nested radicals is a fascinating area of study.

In the expression $2=\sqrt{1+\sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+\sqrt{41+...}}}}}}$ , we can observe a pattern that is reminiscent of the golden ratio. The sequence of numbers inside the square roots, namely 1, 5, 11, 19, 29, 41, and so on, can be represented as a recursive formula: $a_n = 1 + a_{n-1} + a_{n-2}$ . This formula is similar to the one used to generate the Fibonacci sequence, which is closely related to the golden ratio.

Properties of the Infinite Nested Radical

The expression $2=\sqrt{1+\sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+\sqrt{41+...}}}}}}$ has several interesting properties that make it a unique and fascinating mathematical object. Some of these properties include:

Convergence: The sequence of nested radicals converges to a finite value, which is equal to 2.
Monotonicity: The sequence of nested radicals is monotonically increasing, meaning that each subsequent term is greater than the previous one.
Continuity: The sequence of nested radicals is continuous, meaning that small changes in the input values result in small changes in the output values.
