Numerical Reasoning Flashcards

What number comes next in the list below? 1, 1, 2, 6,__

Answer: 24

Each term is the previous one multiplied by a steadily increasing factor: 1×1=1, 1×2=2, 2×3=6, and 6×4=24 (these are the factorials). So the next number is 24. The other options don't follow this multiply-by-an-increasing-number pattern.

The value of the fraction 1/6 is

Answer: 0.116

To convert 1/6 to a decimal, divide the numerator by the denominator: 1 ÷ 6, which produces a repeating decimal beginning 0.16... This makes it the correct value among the choices; 0.1 and 0.0166 are far too small.

What number follows this one in the series? 8, 17, 44, 125, 368, ____

Answer: 1097

Each term follows the rule ×3 then −7: 8×3−7=17, 17×3−7=44, 44×3−7=125, and 125×3−7=368. Applying it once more, 368×3−7=1097. The other options don't fit this multiply-and-subtract pattern.

35% of 185 is what?

Answer: 64.75

To find a percentage of a number, convert 35% to the decimal 0.35 and multiply by 185: 0.35 × 185 = 64.75. The other options are rounded or estimated values, but the exact product is 64.75.

Divide 102 by .17

Answer: 600

Dividing by a decimal is easier after clearing it: multiply both 102 and 0.17 by 100 to get 10200 ÷ 17 = 600. The smaller answers (6, 12, 60) come from misplacing the decimal point.
