I check differences first, then ratios, then squares and cubes, and finally whether two series are mixed together. For example, in 2, 6, 12, 20 the differences are 4, 6, 8, so the next difference is 10 and the next term is 30. I always test the rule on every term before answering.

A syllogism gives two or more statements and asks which conclusions must be true. I draw circles for each group and look for any possible drawing where the conclusion is false. If I can find one, the conclusion does not follow.

I draw the path on paper with north at the top. I treat right turns as clockwise from the current facing direction, and I add north-south and east-west distances separately. Then I combine them, using Pythagoras if both remain, like 3 km and 4 km giving 5 km.
