I found the questions a bit annoying, in an IQ test sense of 'here is a numerical sequence 1,2,4,8,16... what's next?', where you're probably "meant" to say '32', but it could be 31, or indeed anything else. In the absence of more examples of the same sort (i.e. not spread across different questions which could plausibly be related or plausibly not be related), there was really insufficient data to construct an analogy I could be bothered to care about.*

* That's because it was in a non-useful context. If you're learning a language, then you do these contextual deductions, but there are a) plenty of examples and b) the opportunity to check very quickly whether your deduction was correct, or whether you just said there was a frog in your bidet.
