In the ratio 42:56 :: 110:?, what number completes the pattern?
42 = 6x7 and 56 = 7x8 - products of consecutive numbers, one pair shifted from the other. Similarly, 110 = 10x11, so the missing number should be the product of the next pair, 11x12 = 132.
Re-check your working by substituting the answer back into the original question.
