and so on until
118 = (11 x 8) + 2 = 90
119 = (11 x 9) + 2 = 101
And as I said I got it wrong. I used Carl's second algorithm, where 11 is multiplied by the given variable and then you add the sum of the digits.
"Carl's Second Algorithm" does sound like something from a dusty old physics book, doesn't it? Right up there with Newton's Second law of Thermodynamics.

(1) Your answer was just as right as any other that gives the correct results for the first five lines. It wasn't wrong in
any sense of the word.
(2) Forgive me; there is a Second Law of Thermodynamics, but it has nothing whatever to do with Newton's Second Law.
Second Law of Thermodynamics: the entropy of an isolated system never decreases. It may increase, and almost always does; but if it remains constant,
every process going on in the isolated system is thermodynamically reversible. In nature, reversible processes are rare.
Newton's Second Law (of motion): f=ma, force = mass times acceleration.
F, m, and a are all vector quantities.
