Let

$x = 6 + \dfrac1{2 + \dfrac1{6 + \dfrac1{2 + \cdots}}}$

Then

$x = 6 + \dfrac1{2 + \dfrac1x}$

and solving for x gives

$x = 6 + \dfrac x{2x + 1}$

$x = \dfrac{13x + 6}{2x + 1}$

$x(2x+1) = 13x + 6$

$2x^2 + x = 13x + 6$

$2x^2 - 12x - 6 = 0$

$x^2 - 6x - 3 = 0$

By the quadratic formula,

$x = 3 \pm 2\sqrt{3}$

but x must be a positive number, so only the positive square root solution is valid.

$x = 3 + 2\sqrt{3}$

We identify a = c = 3 and b = 2, so a + b + c = 8.
