The numbers below grow far faster than the letters. Which term should replace the question mark?
M5, N10, O20, P40, ?
Answer: B
Correct answer: Q80
The letters advance one place at a time - M, N, O, P - so the next is Q. The numbers double at each step: 5, 10, 20, 40, so the next is 80. The term is Q80. Q60 comes from reading the numbers as growing by a constant 20, which fits the last step but not the earlier ones; checking the first pair as well as the last is what rules it out. A doubling series reaches large numbers quickly, so the arithmetic is worth doing in stages rather than in one step as the terms grow.
