The limit of the sequence is the positive root of the equation $x = 6 - \frac { 1 } { x }$. Solving this equation, we get $x = \frac { 6 + \sqrt { 36 - 4 } } { 2 } = \frac { 6 + \sqrt { 32 } } { 2 } = \frac { 6 + \sqrt { 16 \cdot 2 } } { 2 } = \frac { 6 + 4 \sqrt { 2 } } { 2 } = 3 + 2 \sqrt { 2 } = 3 + 2 \cdot 1.4142135623730951 = 6.8284271247461902$.
