Examples of Real Sequence
The first few terms of the real sequence:
- $S = \sequence {a_n}_{n \mathop \ge 1}$
defined as:
- $a_n = \begin {cases} 2 & : n = 1 \\ \dfrac 1 2 \paren {x_{n - 1} + \dfrac 2 {x_{n - 1} } } & : n > 1 \end {cases}$
are:
- $2, \dfrac 3 2, \dfrac {17} {12}, \dfrac {577} {408}, \dotsc$
