Sorry if this is well known to those who well know it, but the following 
seem not to be in OEIS:

1, 1, 2,  7, 35, 191, 1304, ...
1, 2, 5, 18, 89, 492, 3359, ...

Presumably because I've made a stupid mistake in my hand clculations.

They are the numerators and denominators of the convergents to
the negative continued fraction 1 - 1/(2 - 1/(3 - 1/(4 - ...)))  R.
